With so many sites using vBulletin, PHPBB, UBB, etc. along with PHPNuke, VBAdvanced, vbIndex, vbPortal, etc. it just made sense to have a forum here where we can discuss the issues that come up relating to this software.
If you have any great examples of such forums, questions about 'em, or just opinions on which is better and why, jump on into the discussion!!
