A new forum update is coming soon, and one of the features I'm hyped for are Clubs. Clubs are sub-communities where you can discuss various topics that you define.
From the IPS Community website:
Each club can have their own forums, download categories, blogs, and calendars.
Club owners can add forums where members can create topics. Club leaders and club moderators have control over these forums and can pin, lock, move, merge, and hide threads in these forums.
These screenshots depict a single forum "Topics".
Project Pokémon recently got Blogs. With clubs, you can create a blog managed by the club leaders and club moderators.
Clubs can also have files, similar to our downloads section.
And finally, the calendar.
And who knows? Maybe there'll be something else in there too
