First of all, I enjoyed the design but there are a few things I would improve on. The text in the blue box I would completely make everything bold. Another thing I would change would have to be the navigation I don't mind having a long navigation bar but when you only have few links you're leaving a lot of open space. So I would get rid of the entire navigation or I would extend it with more links. The logo to me has a little too much drop shadow but other than that the logo is fine. With your two ending a footer links I would either align them with the logo or your chat log. Other than that that's about it maybe I would change the background but that's personal preference.
