I teach doctors for a living.. so i take a little different approach. I tell them that there is a better way to get their point across and help if they are receptive. I give them a chance for redemption. If not then they get on the ignore list. Thus my 100% no P.U.G. Policy. Guild choice is so important. The guild i am in Old Timers Guild has very active and involved chapter leaders and officers that quickly deal with frequent violators of good gaming manners.
