Included is a script to handle the subdomains, add new users, allow users to modify their accounts, and an admin script.
Users have the option of a popup, a delay page, or putting the ad code directly on their page.
You have to keep paying for minimum support and you don't have control over the administration. Admin resides in go2cgi server. 1 Don't buy this script. Contrary to claims, there is no extensive documentation, and virtually non-existant tech support. The admin for your script will be totally dependant on their servers - if their server is down, you are stuffed.
