http://adminsboard.com What do you think about the forum? It just launched yesterday, so please bare with me on the member's and post count.
I like the design and the colors, it really looks nice, simple, and the colors are easy on the eye, however I would suggest: 1. To change the logo to a more serious one since the forum is dedicated to webmasters, it is also better to move the logo icon from the left side to the right side, it would look better in my opinion. 2. To remove the banner above the footer, it really miss the deign and looks unprofessional. 3. To add latest news, announcements or banner advertising in the right side since it is empty, and it would look better if it would be occupied with something. 4. To lower the login boxes/buttons, and the register button a little bit from the top, and maybe you can move them a little bit to the left.
Not a bad site - I think you need a more unique theme and definetly a redesign of the logo. How do you plan to differentiate yourself from the existing forums?
I think your forum is looking good and you should add nice logo and header to your forum and get more members to make it popular
