Why are like random letters gray and blue? Are those hotkeys?
I suggest not doing that. It's confusing, and simplicity is also important to a website ('s design). If you are going to do that, make the pattern the same for all parts, meaning don't do like one gray letter and six blue letters in one word, then have like three gray letters and eight blue letters in another. If you keep that gray/blue design, then I suggest making it half and half. WEB/DESIGN.NET looks good with the half and half.
The Navigation bar is a bit clumped. Maybe have a light line between each section and space them out.
I agree with thewrongvine, for a webpage like that, a user would be looking for simplicity. Therefore the blue and grey random lettering should be changed to a more constant pattern, like the beginning letter or something like that.
Again the nav bar definately needs spacing, maybe a faint blue line between them, similar to the other blue lines just not as prominant.
Also maybe curving the edges of the boarder around the nav bar might look pretty good, but then you will need to carry that idea throughout the webpage.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
