Need a PHP script I would assume to allow user registration once they purchase my software program.
User Registration:
When running the bot, the bot has to know whether the user has actually paid for the bot, or if he is using a demo version. The best way to do this in my opinion would be as follows, you must create a script that will create a file with that persons myspace username (eg. [login to view URL]) on completion of purchase. Then when the user logs in to the bot I can just have it check if that username exists on your server (eg. [login to view URL]).
If the file exists, then the user has paid, if not, then the demo restrictions come into effect. This method completely eliminates piracy, since it doesn't use any kind of code or something that can be cracked.
