How many boxes?
2(soon to be 3)

What classes are you currently leveling?
warlock, priest(soon to be another priest)

What software are you using?
Micah's Multibox...I was alt+tabbing before that.

Any fantastic macro's you want to share?
No, I am unfortunately very boring in my macros. I just create 1 kill sequence macro for each box. The casting sequence usually matches up the casting time of spells for both toons to be more efficient.
