Hey everybody, I am looking for some good suggestions for a platform to sell advertising. What I would like is something that can easily be implemented into php pages, with different sized ad units. I know that there are platform specific things for wordpress, etc. but I'm looking to sell advertising across multiple platforms. Also I've taken a look at OpenAds. I'm just looking for other suggestions. -Should be portable to multiple CMS's or any php page -should accept paypal payments (if possible) -Should allow people to pay and instantly upload their banners or text links or whatever Any feedback on this would be really appreciated.
