About Realms(server)

Dear Grinding Gear Games.

Thanks for your reply. I found korean help thread and got information about switching id.
I have one more question so I'd like to ask you.

As you know, POE has many realms based on countries or cities. And we can meet all players no matter whose server is.
Then, in Korea server, can i meet other realm players or not and same as in many existing server, can i meet Korea server players?

Regards Hwan.
