Whitehouse.gov is endorsing the mobile giving program to the Red Cross, and it is set up by an org called mGive, which is waiving the usual fees for all donations. if you have never given by SMS
message, there are some things to know (like you have to tell them to stop texting you alerts and updates)- read the fine print here: http://www.mgive.com/Partners.
Mercy Corps is also endorsed by the Govt. but is asking that donations be given online. All proceeds- 100% go directly to relief! https://donate.mercycorps.org/
I will be spending the day volunteering for Medical Teams International tomorrow- http://www.medicalteams.org/
to expedite the match!
NPO superstar Britt Bravo has compiled a roundup up ways to give here: http://havefundogood.blogspot.
Furthermore, Etsy artists like myself and Ryan Berkley are marking items to go to Haitian relief. So, you can buy art and support folks, why wouldn't you? A simple search using the term "Haiti" on etsy returns pages of results. Be sure to ask the seller to email you his/her donation confirmation. This seems like a really good way to put some art where my mouth is, in lieu of money!
