とりあえずメールの内容の一部をコピペしとくよ。 New account interface being implemented The next step in bringing you the new and improved MyDomain service involves an overhaul of the account management interface. We have begun migrating accounts over to the new interface in batches. There is no action necessary on your part to complete the move of your account. You will be notified by a welcome message upon logging into your account once it has been migrated. All settings will remain unchanged and you will experience no downtime as a result of this upgrade. We are confident you will be pleased with the improvements that have been made. Should you have any questions, however, please feel free to contact MyDomain support or post to the MyDomain forum.
