Humor forum

[goranbaxy]

Hi,
I have a forum that is not on English, but I would like to receive some opinions on how to improve it, visually, or any other tip would be just fine.

It's humor based forum, it's about jokes, games, funny pics... but there are some "normal" sections like sport cars..., but the main categories are humor.

Any review is welcome,
thanks!
