Hello everyone!

Im new to this multiboxing but I did read how to get things started.
Im currently only boxing 2 toons on 1 pc.
My only question(which ive searched) is there a macro on which you can loot a mob?
Because as you know some of the quest require you to gather items from the mobs you kill.
And obviously your main will be able to loot but your alts wont get anything.

So is there a way to do this?

THANKS IN ADVANCE!
