Don't know too much about MySQL but I have managed to create a SIGN UP form and was able to save the input to a database.

NOW, I need to know how I should add the databases for the CONTACT FORM and LOGIN FORM.

Should I use the same database for all the forms and just add tables?

Should I create a separate database for all even though the sign up form and the login form use a few of the same fields? (email, password).
