Tenchimaru Pony: no
Merlin changed mine from Shrike when I first joined and decided to be lazy and stick with one name across all forums… now I’ve got a different one for all of them anyway 
Additionally: http://agora.rpgclassics.com/showgroups.php
Hit on one of those little names in the “Administrators” group and hope they don’t reject you.
Not even all administrators can change nicks. Only Merlin, Zero, Sin, and SK can.
Excellent, thanks.
