Password bug / How to change or reset my password

[Mango]

So before a couple of minutes, I received my beta key, set my account and downloaded the client. I tried to log in but an error message popped up saying "Username or password incorrect". Obviously, my username is the right one. As for the password, I'm afraid I messed it up when setting my account credentials. now I cannot change it because I don't know exactly the one I used to create the account. What can I do to reset it?

EDIT: NEVER MIND GUYS, I LOGGED OFF AND FOUND THE PASSWORD RESET FORM. PROBLEM SOLVED.
