If we join the user base of Windows Live Messenger, Yahoo! Messenger and AOL AIM, we have more than 300 million people around the world.
Plus, if we consider that the best method to communicate/inform about a cause is the mouth-to-mouth.
Then, we have the P2P Donation via Instant Messaging mashup.

My idea consist in a serie of Instant Messenger add-ons that permit the users donate and invite more users to get more information and
donate for a charity through the Network for Good API, giving quick and easy access to donation, and improving the donator experience.

The features of this add-ons are:
* Search for charities or volunteer oportunities
* Share/Tell your friends about a charity
* Make a donation for an specific charity
* Get news/information about the charities that you support
* Use Badges/images/icons for the charities that you support

Please, feel free to leave feedback/suggestions about this idea.
