If you're going to redesign the forum a little bit, here's a few things I've noticed.
The most active forums have places where members and posters will know exactly where all the action is. People that register will be able to see exactly where they can dive right in and start telling fans of rival teams how much they suck, so the fewer the better so conversation is more concentrated.
Anyway, I like this forum
But there is a lot of forum fat I think you could shave.
After you trim some of it I'll pick an epic fight with Flacco. That'll get things moving.
