Hi Shus,
Please don’t worry. IF we have to transfer, we’ll post all details in the forums and send them through in-game mails too, which will persist for 6 months. You can rejoin the Eagles in mid-September or any time you want really.
For the servers on the closing list, players will still be able to access the world till December 31th 2015. Starting January 1st, and indefinitely, players will be able to access former servers only to transfer their characters.
PS: I read the 35+ pages of the lotro forum thread, so you can ask me any questions you have.
Update important from Vyvanne (executive producer): she found an error in the first communique. On Monday, only the characters copies to Bullroarer will open. No free transfers between the 5 remaining worlds for each region. These will open only 1 or 2 weeks later.
