Gone AWOL - sounds like a great idea to me. One thing I'd recommend, though is to go with a less controversial message. The UN thing is just so unbelievable to anyone who's still indoctrinated that they'll probably assume it's a creative lie and not investigate further.
I like the idea of printing up the picture on jwfacts (or on like it) that shows a grandparent with their child and grandchild captioned "how many generations do you see?" Then the address for jwfacts. Since the generation change is still fresh, I feel like that's probably the best thing to go with.
