Storm8 ID and farm name may differ, depending on what players have set. To check Storm8 ID, go to Social list and you'll see it at the top right hand corner of the screen. The Storm8 ID is the same as what we give to others when we invite them as neighbours.
Unfortunately your friend will not be able to check since he cant access his farm and you will not be able to see it via your farm either. But you can check his farm wall and see if he had posted his ID for visitors to add. This ID is essential for recovering our games, I will recommend that alll players set their ID and password regardless whether they join the forum. I'm not sure if Support can help but I will suggest that your friend send an email to
support@storm8.com and see if Support can assist him further. Sorry about this.
