in reply to Checking for Dupes in MySQL

Standard SQL (dunno whether mysql supports it): add a UNIQUE modifier in the CREATE TABLE statement at the e-mail column. Afterwards, your dbase won't allow duplicate e-mail addresses.

Be sure to add decent error-checking to inform your prospective users why their entry was not allowed.

MySQL is SQL92 compliant.
