If you're in the market for a forum system, don't settle for anything until you've tested out SMF. I never thought anybody could pack so many features into a free system, but the developers have somehow managed to accomplish this. This system has just about everything you could ever want in a forum system - polls, a quick reply box, powerful permissions system, powerful template system that's easy to understand, easy-to-use admin center, lots of moderator features (including the ability to split one or more posts into a seperate topic and the ability to merge two or more topics into one) and tons of other goodies, such as XML, RSS and RSS2 feeds, 3 different wireless modes and an automatic mod installer. Simply put, SMF is the most powerful and most feature-packed free forum system out there. Don't settle for anything less.
