Hi, as per the Game Guide subforum rules:
1. Do not create a guide that is asking a question.
As such, I've moved your topic to the proper forum.
To log in on two accounts at once, you'll need to have two copies of the game client on your computer and have them both open. Then you can log into your two accounts on the two clients. You are allowed to do this as long as you aren't breaking any game rules while playing - I'd suggest reading through them here.
yeah i just read what u dont have to do to brake the rules and im sorry to make this here :P thanks tho
