Groups forums are KEY and they absolutely need to have a way of creating multiple topics in each forum as well rather than just a running list of recent discussions.

But what is also 100% key is to have non-group forums as well from same install. That way you can have a traditional forum in addition to group forums which totally makes sense because when you have 100’s of groups it’s impossible to keep track of where things are at like in a traditional forum, so you want to have a balance of both.

Also 100% key is the ability to favorite forum threads. A basic and totally necessary feature to make the current set up slightly more manageable.
