Sorry i don't undestand if i must creat new account (this is my new account on forum) or use old account. for log in in game i use other account. So hard for me!!!
They'll let you know how to transfer your account on march 6th, it's fine that you made a new account for this forum.
Sorry if it wasn't clear. You have to create a new forum account (as you obviously already have). Your game account will be transferred to the DOG servers on March 6th as part of the transition process. You should expect a Customer Service Notice from SOE and DOG within the next few days with more specific instructions.
