Having used phpBB2 & 3, SMF, YaBB, xenForo, to build communitis, and even looked at a few others, vBulletin 4 & 5 IPB I came to a conclusion. None have a decent CMS. I think, in my short 3 years, think Drupal is great, but is severly lacking a threaded discussion (forum) solution. Many say to use a bridge, this is not the place for that discussion. This wiki page is going to be a brainstorming page for general questions that anyone may have. iam not sure how it (the wiki page) will work out, so we can just play it by ear.
For now I have called it 'Colloquium' but feel free to suggest a better name.
