I think a huge improvement would be :

put your ads and banners on a side bar(s)

too much wasted space on the side bars and everything crammed in the top/ middle.

and get rid of that >second< search button

this forum has great content,, but the layout is split up and cluttered

and no offence your not ugly but  do we have to look at your mug on...... every.... single..... page ?
