One thing I did not say was that I may know this person by reputation from a long long time ago. Basically before there was Leeroy from WoW, there was Skeeter from EQ. Where Leeroy was famous for causing a single spectacular accident in WoW, Skeeter was infamous for intentionally causing a chain of incidents in EverQuest. And this guy's name was Skeeter. Now I have no proof he's the same person, but given his actions I have to admit they may very well be one and the same.
No, I am mostly angry with myself for choosing to group up with a potential troublemaker I.
