Unfortunately I do not like the logo very much. The tiny flashing red text just does not fit the site, and the text bubble with the "PTF" in it just does not look right. I would suggest dropping the red text in favor of a static and search engine friendly blurb about the site, expand the PTF a bit and round out the bubble to give it a more comic book text look to it.
The white area to the right in the logo space is very crisp looking, though the Register button seems out of place with the red background.
The forum icons are very generic and do not tie into the site at all. It also looks like the link icons are default. More customised icons based off of the logo would look much better. The buttons do not look like they belong with the style at all and should be updated.
You have a ton of forums and this is spreading your content all over the place. It does look like you have some good traffic but you really want to focus your content into less forums until the community expands and needs more forums.
You are entering into a very competitive and saturated market of general chat forums. You have a good start, keep up the good work
