Thanks

This is a cool community. I like it. Great job bro. Also on the graphics. Nice, clean and crips looking. Very professional at that. Again GJ!

The forum in itself is nice and clean, although there seems to be a competition or confustion over the colour scheme used.
I would probably stick with the primary colours and concepts used in the header and footer personally and continue them throughout the forum.
Or if left as is, i would at least implement the grey gradient or 'bar' on the forum headers rather than the plain colour.
To me this forum currently gives the impression of not finished yet. But what does look complete (the header and footer) looks very nice indeed.
I like the use of the gradient or bar look and the use of 45 degree angles. A very modern and clean look.
