I want to offer ads across about 10 websites, with one script? Is there something available? They're adult sites, adsence doesn't approve.. so I want to offer my own advertising solution.. Originally the ads would be displayed on my own sites, later i'd like to allow other like promoters to opt in. Is there a clone out there somewhere?
http://www.openads.org/ should be able to do what you want. If not, then http://www.phpwebscripts.com/admanagerpro/features.html
