hm, I don't want to criticize you mods, but at least I question that a bit
a new account with low post count... what's too loose for such a user if he just creates a new account?
his 22 posts?
his famous state?
no, a new user actually just can create a new account with the desired name.
a long term user with a high post count can't do the same (at least not without loosing his post count, friends, saved pms, etc. which seems to be important to some people)
so a name change (if at all)seems rather be interesting in case of long time users who actually would loose something from using a new account.
also:
a new user with low post count 'deserves' a name change,though he has likely contributed less...
a long time user who contributed maybe thousands of posts does not?
what's the logic behind this?
