How do I check what server I'm in?

Not sure if I'm in GMS or EU.
How do I check?

Europe Maple should only have 2 worlds. GMS has like 18 worlds, so if you see Scania, Bera, and Broa then that means you are in GMS. If you only see Kradia and Demethos then that means you are in EU.

Scania broa bera windia ETC = GMS
Luna & Reboot only = EU.
Simple
Plus you select one when you enter.. then..
