Hello! I'm from over at OpenX, an open source adserving software. Our 2.5-beta will soon be released as 2.6 (stable) and with it comes the new API for developers. The API lets you control users & banner inventory, grab statistics, and generate invocation tags. We've put a page up to try and help out the development community: openx.org/community/developers I'll be around to help anyone getting started with the API. It might help to PM me to bring my attention to a specific thread. I'm sure people could come up with some creative uses of the API, and please be sure to give us any feedback on improvements/features needed. If you do start using it, please let me know what is the largest stepping stone to get started and how I could help others overcome this. Cheers, Arlen Coupland
