I've got some ideas for improvements.
1. Signatures
All the other forums I go on have them.
2. Private Messaging system
See above
3. Moderators
To make things easier, you could have mods for various areas of the forums. For example, a few for PS2, a few for Xbox, a few for GBA, a few for General Chat, you get the idea, you know, spread the workload. Mods would be able to edit and censor other people's posts, lock off-topic threads, that sort of thing.
10000 posts at last! w00t! Okay, I'm off into a quiet retirement. Don't bother me.
