i was thinking is there any banner exchange service, where that service dont participate in exchange, it just list of sites that wont to find someone who need to exchange theme.
if there is not im thinking to make one.
Ill just put a directorium, like dmoz.org, only in mine webmasters of site are going to put their site in category. Then someone who need banners to exchange go to my page and find category that is his site about and find then another site who wonts to exchange banners.. conntact that dude via email...

what do you think about that ? is there some good site about that ?
