European CM Thundgot announced today that the cooldown periods for both paid character transfer and paid character name changes have been reduced from three months to one month, effective immediately. The transfer cooldown was originally six months when the feature was introduced in June 2006, but was reduced to three in October 2006. In the intervening time, they've looked at server logs and so forth and come to the conclusion that moving it to one month would not have catastrophic consequences.
This change appears to be effective on the US realms as well, so wherever you are, you can hop servers and adopt new aliases every month if you want to pay for it. Also, Thundy clarifies that as long as your last transfer/name change was at least 30 days ago, you are immediately eligible for transfer/name change now. He also said that "moving forward" the price for paid transfer is going to be 20€/£15, but given his phrasing and the fact that I'm on the North American realms, I can't tell if that pricing is new or not. Do any of you know? Edit: Not new; thanks.
