But if you are expecting support, or even a single question answered, good luck. Its as it the people just walked away from this project as soon as they released it. With the exception of 4 posts made in August 08, there has been absolutely no activity by the developer.
Other than that I figure out how to use it and it works ok, with a few bugs. It actually has a lot of potential as it allows very precise targeting of ads, but with no development I am afraid to use it on a production site anymore for fear of security issues. I hope they pick it up again someday, but for now it appears dead.
