Here is a great way of using the internet and social networking to find some local help for any family crisis. lotsahelpinghands.com
Lotsa Helping Hands is designed with the understanding of how to bring together a variety of social circles and what a resulting community like this would need.
You basically set up a social community on this website and give access to any helping members who can then all communicate and coordinate schedules, etc.
This is what I love about the internet. It gives new and better ways to work together.
