Make Them Pay
Times are tough, and it's becoming more common for grown children to be living with their parents. If you have a kid returning to the nest, it's time to set some ground rules. Curfew will likely be a thing of the past, but more will be expected in return. You don't necessarily need to charge rent (the more they pay you, the less they'll be saving to move out, right?), but your child should help out in some way -- utilities, grocery shopping and cooking meals, household chores, etc. Set a time frame for moving out, and make sure he or she has a financial and employment plan.
