A short while ago I received an email from an old friend, mentioning another excellent channel for providing immediate assistance to Haiti; with the added bonus that whatever you give will be doubled. I quote it more or less in full :
Medair brings life-saving relief and rehabilitation to disasters and conflict areas. They are currently working in Afghanistan, Congo, Madagascar, Somalia, Sudan and Uganda - and already have a team en route to Haiti. I worked for Medair in Kosovo ten years ago and am now a UK board member, so I can vouch for their expertise and integrity. And thanks to match funding from The Big Give, donating online at www.medair.org/x2 will mean that your donation is doubled immediately.
I appreciate that Medair is not a Catholic charity - it is a Swiss NGO - but it does excellent work, and in view of the match funding offer, it must be worth at least looking at. You can find out more about Medair here.
