Ok... I have the ID thing working.. kinda. Am I supposed to set a default value because i don't have anything there. Then, when i create the table it puts 0 as its default and when people sign up, the id for each person is 0.
it would seem like you didnt even have to come and ask as you already know what you must do.
the length can be 1, as no more than one is needed cause it only auto_increments by one per row. People usually set it as the primary key, everything else I think you know
