Client Background Color
Site is cool, easy on the eyes, but annoying that the background image does not extend all the way down behind longer forum sub domains when displayed within the client. Possible correction: sample the bottom row pixels of the background image, average the color if necessary then set the client background color (behind the image) to the color sample taken on the fly; the solution would make the system dynamic with little effort and capable of updating along side any changes made in the future less impacting negatively.
The white background color, considering the background image and font color, is a no go. Accessibility also includes good color separation for visual distinction especially when considering inviduals with visual challenges or impairment. Thnx for your consideration regarding this matter.
