Co-Reg Master

Co-Reg Master lets you add co-registrations to your all your forms (even the ones processed by third-party services, like SuperTaf) by simply cutting and pasting two lines of HTML. No coding is necessary, and co-regs can be processed in many ways: by sending the registration info by e-mail, passing it to another script (either via GET or POST methods), or by writing it to a database. It is great to build large opt-in lists very quickly, and also to earn some good extra income by selling coregistration ad space.
