Combine accounts

I'm fairly certain that this mountainproject.com/u/mark/… is my account, transferred over from the climbing boulder.com website when MP first started. It might even have my old earthlink.net e-mail address associated with it. Unfortunately I seem to have forgotten the password. At any rate, I would like to go back to using just my first name. Is there some way we can merge this account with my current account? Thanks.

The email is one from hotmail. To change your name, have you tried just going into 'change personal info' on your personal page?
