As reported on the WoW LJ community, selected realms are getting free transfers to lower population realms. I will admit to being a tad disappointed that the realm where most of my alliance characters languish isn't one of those realms. But for the inhabitants of a super-crowded realm this can only be good news, and I congratulate you all for getting a chance to move while the offer is open.
The complete list of realms who will be getting these transfers and the destination realms will be presented after the jump in case you can't access the links for one reason or another. If you are on one of the realms being offered the move, you have from Thursday, December 6th to Thursday the 13th to get your bags packed and make the trip to your new homes.
