Kareyev is Vaslov, correct.
I'll add Jelodia to Harbromm's friends list so that I can give an invite (it'll be nice to have another Paladin and another smith!). Also you can look for Garos who also has the power to invite (as will Vaslov pretty soon).
As for EN World guilds on other servers, go for it! I'm not claiming a monopoly by any means. Change the name, change the tabard, change whatever. I don't think I'm going to be making an alt on another server, but I'm totally cool with other members of Enduring Nobility traveling wherever.
Finally, I'd like to formally announce an intra-guild dueling competition to be held this Saturday (Feb. 19th) at 2pm Central time. We'll be holding it where the frozen lake meets the river at Dun Murogh, close to Brenwall Village. To get there, leave Ironforge, travel down the path to the riverbed, go west along the riverbed until it widens into the frozen lake. The area is almost completely free of angry wolves and such, so don't worry. I've had duelling practice with a pair of Hunters from Silver Dragon--the largest guild on the server I believe (level 56 and 60, they taught me a few things)--there without interruption, it's a nice, open place to meet. The competition will be a chance for you to learn a little about dueling if you don't have much experience. We'll be organizing matches according to level and I'm sure I can dig up something in my vault or coinpurse for prizes (though the coinpurse is a tad light since I hit 46 and had to train...). Besides, it'll be fun to watch a certain level 46 Paladin have his weaknesses exploited by a certain Druid and Warlock. And let's thank Lt. Garos for the idea!
