I'll Scratch your Back if you Scratch Mine!

OR...I'll help organize your closet if you help organize mine!  I just recently bought Real Simple magazine, an organizing edition (of course!), and it had this really cool idea!  Basically, they said to have a friend help you and you help them, then you go out and celebrate together!  It sounded great to me, but a closet is not what I need help with...more like my attic or my basement.  Who's coming over??
