I had same idea 1 year ago, moved my priest to WOW2 so that I could do more stuff together with my mage. Downloaded ISBoxer and 2-box went to 3-box added a tank. Eventually started full party. Now have done several teams, also in classic. But yes it is quite a learning curve, often you are more 'playing' ISBoxer rather than Wow itself. It might not be for everyone.

So if you want to start simply, consider LevelBuddy
