I do not think there is a way to reset your password (I made a -few- accounts acccidently) nor is there any way to delete accounts at this point, to my knowledge. They may be implemented later on, but currently the game itself it low security in terms of accounts (come on, the email is optional) maybe you could pm an admin about reseting your account password for you.
Note that all the above could be wrong ^^
In which case, let me now what you figure out, I think my accounts are in the two digit numbers( I feel guilty about taking so many names) And my account i'm playing on, well, I'm really suprised I remember the password.
Short version: You're hosed, I speak from experiance.
