Event Registration System:
This would be an event registration system where a form would be created in the backend and users can fill it out (form would be customized by admin). (each available "event" would have its own form. The ability to duplicate a previous form would be very helpful!).

An option to require a payment for the event should also be available (as well as a "Cash on Delivery" option). An option to allow for a deposit, and for a user to log in and supply additional payments should also be given.

This script would be very versatile as it can be used to sign up people for classes, camps, concerts, and a variety of other events. If it could be tied into the shopping cart that would be even better!
