I duno why ppl here are screaming about red color. I dont see any wrong/discomfort with red. Blue is common. Red is unique. Current theme isnt completely red there is a blend of grey , black, white red.
But I prefer fluid forum. This isnt fair to force ads on right side of forum, as our eyes have to focus on left side completely, quite annoying. fonts are also not so good. Definitely there seems some improvement but still lot of room there to get more elegant.
As every1 suggested...dark red/brown more desirable than current bolded red fonts.
