I'm not sure how to say it, but let's try. There is a default option wich allow user to use Paypal for upgrade, but I would like to use something else called Starpass. I know that I will have to create a PHP page when the codes they entered on the Starpass script are good to move my users to a certain "usergroup". Else, there is a default error.php page. The question is, how could I make this PHP page to add my users who paid to another usergroup? Like, how the code will look? This is a basic question I think, but i'm totally noob with that. Thank you in advance.
