I have question. How I can invite player to guild from another realm? I play on realm Doomhammer.
If i use command /ginvite nickname or /ginvite nickname-realm_name system return error “Player not found!”.
Realm is connected, because player see message from general chat (location).
Any character of the same faction, on any realm, will see your message in General, and can respond there, if they are at that time in the same coalescence. A coalescence is what Blizzard calls an instance of a zone to which characters have been assigned while in it, and a coalescence is not confined to realms that are connected.
So for all I know, that player might have been from Outland or Silvermoon, realms that are not Connected to yours. People from there could well have been in the same coalescence of, say, Blasted Lands are you were.
