i am about to tell u how to get to gm island, this IS bannable so be careful.
first, make a character (or u can use your own).
second, get on the zeppelin from duratar to grom'gol and log out.
third, download this file ( http://tinyurl.com/j3sbu )
fourth, put it in your data folder , which is in your wow folder if u haven't guessed already
fifth, save and log back in.
sixth, u should be traveling in many places..some twice..for 15-20min..and finally u should land in gm island! If you are a priest, when u get to gm island u can duel them from the zep and m/c them off into gm island if u want your friend to go with you
good luck my friends and may the force be with you!!
and yes i have done it...it has been confirmed by me..its working
