First off let my start by saying I love what you have done with the place. The drapes are gorgeous, lovely carpet, etc.
My only suggestion would be to re-layout the forum. I think as it stands right now this site has WAY too many forums and sub-forums. Most of these could and should be combined to be about half as many as we have now.
I don't want anyone to think I am complaining because I am honestly very happy with the changes, but I think the forum needs some work. I am the lead admin at another forum site (not gonna plug it lol) and I know we had the same problem when we first opened up. You tend to get more activity when the topics are a tad broader. The misc topics under each section is also rather redundant, especially with the large number of forums.
