So I don't know if I should put this here or in mysql, but what my script is for is for people to add their emails to our mailing list. Pretty simple, I got that working. But what I want it do now is that if somebody puts their email in and their email is already added to our database then it doesn't do anything. but if their email isn't in our database then it will add it.
