This is kind of on topic, although not completely on topic. I also (in the ongoing adventure that is multiboxing) ran across more and more keys I needed to add to my do not pass list. One that I completely forgot to pass was TAB!!! I wondered why 1 of them would always "randomly" target things as opposed to the leader. Took me to lvl 45ish to figure it out.

Having just gotten 70 (and flying mounts) over the weekend I'm about to add spacebar to the DNP list as well, it'll make following while on a flying mount easier I believe.... BUT JUMPING + MULTIBOX=FUN!
