You can change your location under "My account" - "edit profile"
When Tarrant changed some aspects of the site, some locations were lost.
If you recall I was an Elf from Beleriand as my name would suggest. So some of us have different identities from when we first joined PT.
If any council members are there, any chance finding Beleriand again? I know it sank under the sea, but lets not be too pedantic.
7) Removed a number of previously available locations temporarily, until they can be added to the weather system. 600 or more members were assigned random locations, if this was you, you can go to edit profile and move to a different location of your choice.
(This is from the thread I linked to earlier)
I wouldn't worry, I'm pretty sure Beleriand will be back on the list when Tarrant has finished.
