This site has been under nobody care for 3 months ,now renovate by me. http://directory.doctornuke.com It's PR 4 and main category has PR as well. Thanks
to be honest i stayed for less than 10 seconds you want a succesful directory lose the adsense the thing a submitter wants to see is not a big block of adsense
The header area looks awkward... center your site's title and change the font color to white so it can be more legible.
I like the clean look. There seems to be too much content on the front page though. Submit button doesn't work?
