Bahahaha. Edi, please don't take this seriously. diplomat is the resident troll.
That said, this is libel and Edi shouldn't have to defend himself against such an accusation as though the accusation carried any weight at all. Simply addressing the situation almost gives it the credence that it's a significant possibility that Edi is some sort of internet stalker.
As someone who has already given Edi my information and am still alive and well and have not had any suspicious charges to my credit card, I can say that the worst that can happen to you if you give Edi your contact information is that he sends you a board to help you start up a Diplomacy community in your area as well as hooking you up with fellow Diplomacy players in your area.
diplomat, if you feel uncomfortable giving your information out, that is fair enough, and in many cases it is the prudent way to go. However, the solution is simple. Just say, "No thanks. I feel uncomfortable giving out my information over the internet." There's no need to bring drama into the equation, let alone slander a very well established player.
With that said, I would say there is no rule against outside communication and it might even be encouraged. I know that I welcome Diplomacy over instant messaging because it's much more effective. The only danger is that you don't allow the relationship you will probably build to turn you to metagaming. It's all well to use as a tool for Diplomacy but don't use the relationship to immediately ally in the next game. Be prepared to stab, and especially be prepared to be stabbed.
But back to the issue at hand. diplomat, you have to understand that you can't keep posting like this. I wouldn't be surprised if Kestas banned you at this point, and I would not be against it. It would be a shame if you're a legitimate player, but I think you're deteriorating the experiences of others on this site. If he does, you're welcome to re-join under a new alias to avoid the flak that comes now by carrying your username, but I would definitely refrain from posting too much in the forum and completely stop starting new threads.
