I really hate forums who have strict signature rules cause it doesn't allow for as much creativity so I'm glad this one allows for bigger signatures. Though I can agree with people here saying that some people's signatures are a bit too big. Though again I don't think the signature limits should be cut back too much cause it does allow for some nice signatures. 600x250 at the most or 600x300 is good too imo.
Other than that, I can't think of much else that can be changed. I like how a lot of idea on this forum are being implemented and I'm satisfied with how the forum's being ran right now.
