I have been trying to add some usernames and character number
codes and so far I have been able to add "Grim 517". So far I am
unsuccessful in adding other usernames.
Do you think my Australian version of Starcraft 2 is Region locked
and I can't play American players?
Yeah I believe it's region locked to the Asian servers. Blizzard mentioned that it is looking into alternatives for the Australians to connect to NA. Hope to see you soon /s
