Really?
I use a discontinued cheap version of a script $30.00. The guy's head got hot and he is selling
another version for $249.00. It supposed to be better than mine, but mine does the job just fine. I have all the zones setup, and when someone selects one and pays, the IPN returns to my site and activate ad automatically.
It displays banner, texts etc... just like googles and more.
For texts I use with Nexyalis hack and it displays in all showthreads, can't miss it.
