The "Dumb Lem" account doesn't seem to exist on this iteration on the forums. We've moved several times, and accounts were preserved in the LemmingsForums.com -> LemmingsForums.net move but not in any other move.
The "Xan Kriegor" account is still there. Can you confirm to me (via private message, not publicly) what the email address is, what geographical location you would have been in when you last used that account, and what the actual username you used to log in may have been? (Even if you don't know all of these, confirm the ones that you do.)
