Your main page irritates me. The title is stuck dead where it is (don't flex).. and the two columns below it jump around when the page is resized.
I don't like the .. well what ever that is applied to teh name.
I do not like how "Members in the last 24 hrs: 32" runs on top of the logo.
I do not like how the logo isn't a link back to the main page.
I don't like how there is zero 'about' page or FAQ.
I do like how there are some sort of screen shots at the bottom.
Where's the copyright footer?
No news page?
Finally - the concept is really just played out. I don't know what distinguishes this site versus any othe umpteen million others.
I think you are in deep need of some kind of alignment. At the moment the content is all over the place in relation to the title header. The header needs to move with the content to make it feel like its actually a part of the page.
Well, it needs more contrast. A proper footer and header should be added as well. If you plan on having that information displayed on the right side ( right bar ), needs to be defined below the header. Overall decent site although more symmetry is needed.
