For someone to do something like this they must have had a reason to do so. Do you have an IP for this stringy account and why don't your cross check it with everyone else? I don't see who would do something as obscure as edit one of Zapsta's posts for no reason.
By the way, whose posts/signatures has he edited? Just to help us to see what kind of person this man is...
is it really this important now?
So, stringy is wbl?
So wbl is someone who dislikes Zapsta? And Vienna?
And would also be able to use the TSR AdminCP, or get into it somehow?
I think I could give it a guess.
