Well i kinda like it.
The only suggestion and not becuase this forum has it is that i would have your advertisements / greetings message on the right hadn side, it's only because i'm used to everything being on my left :? But thats probably just my preference.
The login box on the rop right hand corner could do with blending a little better. Don't know how they are done on VB
but it looks kinda nasty with the boxes roudn them.
I'm a big fan of using a grey scale site, different tones of grey and black and white i really like that!
In terms of features have you got Rep, Signatures and rating systems?
One thing i've been working on a site i'm building is a "performer of the week" type thing.
Essentially i'm working on a site (don't mean to hi-jack but it will make more sense if i explain, and i won't link at all). But i'm working on a site where users register and post songs / tracks for other people to see and view (primarily DJs) now the tracks can have comments against them and be rated out of 10. I PLAN to do a feature where each week i will run a report (automated) against all of the tracks submitted by users and the user with the average highest track rating will get a promotional spot on the site, So it might be that they get to submit 1 track to the website that for 1 week will stay at the top of all of the listings, so more people "should" look at it. This can be a track they really like or even a track they have created.
I'm not sure how this translates to your forum or how you would implement it on a forum, mine is going to be comepletely MS SQL based so I can just auto generate that priviledge to a user by running a job on a SQL Agent. Don't know how you can do this on VB
