[mw-devel] Password overriding in mw(?)

[Andrew Price]

A user named mark recently started using mw and he wasn't asked to
register and he wasn't asked for a password when he ran mw. It seems
that someone has used the mw username "mark" in the past and this new
member has taken over that mw username and all its settings because his
account username is "mark" and mw forgot about asking him for a password
except he can't change the password now because it wasn't set by him.

What the...?
