Can't access my old account

I briefly joined this site a year ago and was thinking about rejoining, but can't seem to remember the password for my old account/I don't recognize the email that's tied to the account either. 

link to the account is here. 

Would it be possible for a staff member to alter the password of the account so that I can use it? 

I'd also like to re-activate my old character if that is possible, but I haven't managed to find the rules involving that yet.
