guest account??

highway1

Im very very new to mmorpgs, but a few of my friends seemed to be addicted to WoW so i wanted to give it a try. However, Id really like to try it before i buy it so can anyone here let me use their "guest account" that apparantly comes with the game. I asked my friends but theyve already used their's so itd be great if someone here can help me out. THX
