Hi pileofrogs, What I'm trying to do is the following...allow users to add themselves to a flat database which looks like this(split with an "=" sign): 
user1@website.com=users name 1
user2@website.com=users name 2
user3@website.com=users name 3
user4@website.com=users name 4

If a user tries to add themselves, using an email address that already exists in the database, then they are told to use a different email....If the email doesn't exist in the database then the email and name are added.
