InVending Donations

A vending machine that uses the traffic light system to label various food options. The machine still sells junk food like chips and soda, but it adds a 5-cent surcharge for each one, which is then donated. The University of Virginia is already using one and managed to collect $7,000 which was donated to a children's fitness clinic. Not bad idea for collecting money!

post your blood group info on your profile

it be a good idea to have blood group information on social networking sites, people post all sorts of personal/career info, friends of friends can contact you and ask you if you would be willing to donate blood for a friend, you never know when you will be in an emergency. searching via friend networks across many different social networking sites can help find people with the right blood type you need.
