I dont know about you but ive always wanted to control other chars with simple wow commands and it hasnt been possible. Until now!

I found Voodoo http://wow.curse.com/downloads/details/13497/ whilst randomly browsing curse. Heres some of the features:

Allows non-leaders to invite people to a 5man using !voodoo invite <name>

Allows users running the addon to be commanded to follow, roll or logout e.t.c

None of these actions can be performed unless you give someone permission first so no need to worry about people exploiting it. I will be testing out this addon soon.
