So I'm not sure where I should ask this, but I've noticed a lot of threads have several tabs.  Namely IC, OOC, and Character Sheets.
How do these work?  Is it at all possible to customize them?  I didn't really want to make a trash post just to test.

The RP I'm looking around to move is large enough that we use a sub-plot campaign structure, where characters break of in groups of 3-6 and work through small campaign arcs run by sub-GM volunteers.  In the current forum we're in the biggest reason we haven't moved is that we've got a dedicated subforum folder due to the multitude of thread we create getting lost or clogged in the standard RP section.

If it was possible to make custom tabs we could just have a master thread for each sub-plot set with each tab listing one of the subplots.

I was going to respond to this last night, but I was too tired. Hopefully I can answer your inquiry anyway. . . 

From my understanding, you can't exactly customize them though you can utilize [url=https://www.roleplayerguild.com/bbcode]BBCode[/url], [url=https://fontmeme.com/]headers[/url], and so on to make your Roleplays look more presentable. You can find guides for "prettying up" your Roleplays [url=https://www.roleplayerguild.com/topics/162563-articles-and-guides-index-updated-april-5th-2019-notify-lady-a-to-g/ooc]here[/url]. There is also what's referred to as a "zeroth post" on the OOC and Character tabs that can be stickied for important information such as summaries, lore, character lists, and so on. It may be easier to peruse the forums to see it in action as opposed to explaining it though. I wouldn't worry too much about making a "trash thread" though as if you're ever unsatisfied with your work, you can request it to be deleted by moderators [url=https://www.roleplayerguild.com/forums/9-suggestions-problems]here[/url].

Hopefully this helped a little!
