Yes I've bought the game and it seems some of the local fur community as well as a few others will be playing on Maguuma, so I'll be playing on that server for now. As far as I understand world transfers will be free for as many times as you like for the first little bit until ArenaNet decides the populations have settled enough and begin charging for them, so friends can either transfer to Maguuma or perhaps I could be convinced to change worlds myself.
