I got a question that i need help on.
1. In my authentication menu is their any way for me to prevent automated registrations.

2. If I get two customers; the 1st customer (already a menber) and has the username=john and password=smith for their account and the 2nd customer (who will try to create a new account with that same username and password) once submit is entered, I get a page that displayes server error, anyone know what to do with that.
