Look for some places to run AD's for http://www.techiestalk.com a forum. If any one has a site that is targeted to tech users or some thing like hostingtech.com and sell banners post pricing or give me a link we are looking to run a lot of AD's here very soon to get the site moving even more..
I run a Racing games network, racerplanet.com 50,000+ page views a day to 6,000+ unique visitors daily. We're mainly savy gamer's into computer's, car's and racing. Contact me via email if you want more info, I don't stop by here that often.
