Heres a list of forum software that I have used in the past: XenForo (Premium) Active license IPB (Premium) License sold long time ago vBulletin (Premium) License sold long time ago MyBB (Free) phpBB (Free) SMF (Free) Out of all these my two favorites is XenForo, and MyBB. XenForo is the best Premium alternative, and MyBB is the best free alternative. Just my opinion. Freeforum hosts don't count by the way as they are not scripts/software. Also, only post scripts that you have actually used on a live site, and not the ones you *tested* and/or been staff on, because you really didn't use it.
