I like the theme and colors at lot, but at first glance it's very hard to see what's a link, what's a title, and what's content. I might try making all links / titles blue with a slightly darker or lighter background. Also the logo is 187px tall which is a little much. It will push the actual forum content farther down on the page and people will need to scroll past it to see the forum posts. Maybe cut off a little of the background so it isn't so tall.

Maybe try something like the image I attached, it might help break up the page into sections. you'll need to cut the image first, but I made it 500px wide just so you can see what I mean.

The actual forums them self are fine, but the area above is a little messy. Also don't forget a fav icon.

Edit: One last thing, the time is purple, try #666E86, same saturation and brightness, but a blue hue instead of purple.
