Hey guys, I know I am probably bringing up an old which was asked in the past but I would like to see if anyones views have changed or they have a better input. Okay so firstly i am going to ask has anyone used a clone of an ad network? eg adbrite clone If so what were your major issues and was it successful? What is a pro and con list of starting and running an ad network? Start up costs in a detail form not a quote like "you need alot of money" LOL and yeah just any other info just interested in the concept wouldn't jump in because I want to expand my knowledge of web development. Anyways thanks for anyone who posts some help info Best Regards Jerry
