2 Characters 1 Pc...how to..

Hi mates, something that I did not found in the forum, not been mentioned about is to start 2 Wow sessions so to lunch 2 Characters and the the best solution to control them..
Iam using since a couple of weeks the last version of jamba addon.
But it is not working how it should, sometimes something works sometimes not quite radomly would say .
Actually I do not need complicated staff, :D i would like that one pg follows the other, that the priest is able to heal the lock, do farming togheter...do you have any suggestions ? Thanks in advance

i could be misreading this, but are you talking about running more than one window of wow on one pc? as in multiboxing basics? your just launching more than one window of wow, but you need multiple accounts to launch. you cant log into 2 characters from the same account.
