Forum

The forum is the hub's message board: the place for a conversation that has no single right answer, held in public, where whoever arrives next can read it. A materials group argues out which exchange-correlation functional to trust for a family of compounds, three people weigh in over a fortnight, and the thread stays on the hub as the record of why the group settled where it did. Nothing about that fits a question with one accepted answer or a ticket that gets closed.

If you only want to know whether the hub has a forum and where it is: it is at /forum, most hubs link it from the community or support menu, and you can read it without an account if the hub allows it. Posting always requires you to log in.

Discussions are grouped into sections, each section holds categories, and each category holds discussions — a thread made up of an opening post and the replies to it. Groups have their own forums, described in Group forum.

Which one do I want?

Four parts of the hub take a written message from a member, and it is easy to file in the wrong one. The forum is the one that never closes.

A forum thread has no accepted answer, no assignee, and no state that says it is finished. That is a feature when the subject is a method, a convention, or an argument, and a nuisance when you have a broken tool and need someone to fix it. If your post ends in "is this a bug?", file a support ticket instead: nobody is on duty to read the forum.

Finding a discussion

The forum's front page lists every section with the categories inside it. Each category row shows its description, how many discussions it holds, and how many posts. A padlock in place of the folder icon means the category is locked: you can read it, but you cannot start a new discussion there.

The sidebar carries a Statistics panel counting the categories, discussions, and posts on the hub, and a Last Post panel linking to the most recent post anyone has made.

The search box at the top matches your words against post titles and post text. Press Search to run it; results list the matching posts with the section and category each one lives in.

Click a category to see its discussions. Every discussion shows its title, who started it and when, how many posts it holds, and who posted last. Sort the list with the Created, Activity, # Posts, and Title links — clicking the active one again reverses the order. Two icons mark special discussions: an asterisk for a sticky discussion, which is pinned to the top of the list regardless of age, and a padlock for a closed one, which no longer accepts posts. All categories takes you back to the front page.

Every discussion has an address you can share: https://<your hub>/forum/<section>/<category>/<id>.

Reading a discussion

Posts run oldest to newest, each with the author's name and picture, the time it was posted, and an Edited stamp if it has been changed since. The @/on timestamp beside a post is a permalink to that post. Where the hub has turned on nested threads, replies are indented under the post they answer.

The sidebar of a discussion lists Tags On This Discussion, In This Discussion — everyone who has posted, with anonymous posters shown once as Anonymous — and Attachments, every file attached anywhere in the thread.

If you are logged in, a heart under each post lets you like it. The count beside it opens the list of everyone who has liked that post, with links to their profiles. Click the heart again to take your like back.

Posting a reply

The Add Post form sits at the foot of every open discussion. Log in, write your post in the Comments editor, and press Submit. Guests see "You must be logged in to comment." in place of the form, and a closed discussion has no form at all.

  • Type an @ in the editor to mention another member. The name becomes a link to their profile, and they are emailed a copy of your post.
  • Add Your tags to connect the discussion to other tagged content on the hub.
  • Attach one file with File, optionally naming it in Description.
  • Check Post Anonymously to keep your name off the post, if the hub allows it. Hub managers can still see who posted.

Where nested threads are enabled, each post also carries a Reply link that opens a small form directly under it, so your answer is attached to that post rather than to the end of the discussion. Nesting stops at the depth the hub has set.

Starting a discussion

Say you want the functional argument on the record. You open /forum, find the section your hub uses for simulation topics, click into the category inside it that covers methods, and press New Discussion in the sidebar. Posting into the category you are already reading is the whole trick — the form starts with that category selected.

  1. Press New Discussion. The button is absent when the category is locked, and you are sent to the log-in page if you are not signed in.
  2. Fill in the form below. Category and Comments are required; everything else is optional.
  3. Press Submit.

The hub confirms with "You have successfully created a new discussion topic." and drops you into the new discussion, where you can copy its address out of the browser and paste it into your group's chat.

Field Notes
Who can read this thread? The access level needed to read it — Public, Registered, or another level the hub defines.
Category Required. The menu lists every category you can post in, grouped by section.
Title The subject line of the discussion.
Comments Required. The opening post, with the same @ mentions as a reply.
Your tags Optional keywords.
File, Description One attachment, with an optional description.
Post Anonymously Hides your name, if the hub allows anonymous posts.

Forum moderators also get Make discussion sticky and Closed thread (no new posts) on this form.

If a discussion lands in the wrong category, press Edit on the opening post: the Category menu comes back and choosing another one moves the whole thread. The menu on a reply is hidden, because a reply always follows its discussion.

Editing and deleting

Your own discussions and posts carry Edit and Delete links. Editing reopens the same form; the post is stamped as edited afterwards. Deleting asks you to confirm, then hides the post and everything under it — replies to a deleted opening post go with it.

Reporting a post

Every post has a Report abuse link. It opens the hub's abuse form, and once a post is reported its text is replaced on the site by "This comment has been reported as abusive and/or containing inappropriate content." until the hub's support staff review it.

Managing categories and sections

Some hubs let members organise the forum as well as post in it. When yours does, the front page grows a New Section form in the sidebar and a New Category button under each section, and sections and categories gain Edit and Delete icons.

Creating a category asks for a title, a description, who can see it, and the section it belongs to. Lock Category (no new posts) closes it to new discussions while leaving what is already there readable.

If the forum is completely empty and you may create sections, the front page offers to generate an example section and category for you to start from.

Elsewhere on the hub

A group's forum works the same way but is reached from the group's Forum tab, is limited to the group's members, and can email you new posts — individually or as a daily, weekly, or monthly digest. See Group forum. A lab that wants its method arguments kept among its own people wants that one rather than this one: the hub forum has no way to restrict a discussion to a named set of readers beyond the access levels the hub defines.

For a question that wants a single answer rather than a discussion, use Questions and answers. To reach the hub's staff about something broken, use Support. To ask for something to be built, use the wish list.
