Hello there,
I've just had a quick look at your site.
The main site has a nice, clean layout. Looks good to me!
However, the banner could do with a little work - the background looks great, except that it's cut off on the right hand side, which is a shame.
The text needs to be sorted out - "Youngistan" is too dark on the left hand side, and gets lost with the background.
Also, the text in the banner is too pixely. It looks really, really bad I'm sorry to say.
I also had a quick look at your forum, which surely must be the biggest forum I've ever come across

There seems to be something for everyone!
Again, the logo on your forum is a little pixely - it's not as bad as the other one, but could do with attention.
Otherwise, it all looks good to me, and displays well in Firefox.
