Welcome!
Did you ever post to a.r.s?
Just wondering...thought I recognized your nick but I could be wrong.
The local OSA troll on de.soc.weltanschauung.scientology (the German equivalent of a.r.s) uses the nic "sharky" and he occasionally (cross-)posted on a.r.s, too. So, I think that's why the nic might sound familiar to you.
I'm not giving away any secrets here, when I say that that "sharky"s real name is Gerhard Waterkamp, a Church-Scientologist, who left Germany because of alleged "religious persecution" and now trolls d.s.w.s. from somewhere in Florida (Clearwater?)
I don't think, however, that this Sharky is Gerhard Waterkamp.
Anyways, welcome, Sharky.
