I was thinking that now my friend is level 30, I want to see what server he is on and also message him from my server. Is there a way to do this? If not that's totally fine.
You can see what server your friend is on, just send him a friend request by /friend <Username> Whe, your friend accepts it you can /friend and it tells you what server your friend is on.
Like mentioned above, you can easily send your friend a friend request, and once they are added to your friends list, you can /friend to see which server your friends are on. However at the moment you cannot message them from a random server, and you must join their server in order to message them.
I've tried and it says Offline even though they are just on a different server (I'm on 15, friend on 14)
