Re: How to create a forum that isn't associated with a group?
This all depends on what you want your website to be about.
I’m guessing that you can modify the groups heavily so that they’re believed to be forum categories instead. Strip everything but the forums from the groups (members, admin, all) and change the way they look. The forums should be more prominent and have larger fonts, etc.
The downside is that all the groups-features will be unusable. At this time I’ll probably try to make this change and see what happens. It will be a modified groups child theme oriented at forums.
I’m all for integrated solutions and don’t want to have a bridge. They tend to collapse from time to time (at least back in the phpBB2 days).
