Good site, i like it .. let me give you my opinion based on the design aspect.. Your site is designed efficiently , but not attractive ... I like your use of colors but i gets boring very quick i understand is a webmaster forum.. but i would say to add an interesting background , that gray is just boring.. perhaps a gradient from top , or an image , take this site for example..
Another thing is i noticed , the huge REGISTER box.. it gets VERY annoying after the first page , you should consider only having it on the home page , and then add a smaller version on the rest of the pages... hmm like my site for example (

You should consider a navigation for the site , to link to the most important and interesting parts of your website , BLOGS.. Videos... Resources... etc...
its a good site but it can be better.
