hook up with a friend, have them level your toon while you are away. you will come back in a week to find your char stuck on a tree at lvl 32 or something crazy like that.
if you are determined to level afk for a week i'd suggest this combo:
logmeout set to log out on afk, stucks, whispers, all the regular boxes. click the box 'hearth and exit' on the second page. the reason you 'hearth and exit' it will start the run to the questing area over so if you are stupid stuck, like in a building, flying in a tree, stuck on a tree, in a bush, on a corpse, or imaginary something hb detects but won't jump over. then you will run back and be unstuck.
relogger set to relog for a set time, personally i run noon-6pm and 8pm-2am. gives me 12 hours of good play time. split like a 12 year old player with 2 hours for lunch.
