I recently signed up for this sponsorship thing from Plan-UK. Seems like a decent thing to do, and if you register for a tax refund when you sign up, they can claim an extra 20% on top of what you give them. Excellent people, wonderful projects.
You get a lovely welcome pack with a letter from a worker who's recently visited your sponsored child, a map of the area where the child lives, and a photo or two of the child themselves. I'll scan in the photos I was sent and post them here eventually.
Plan-UK do some great work around the world, focussing on education and sanitation for the most at-risk children. Please have a look at their website and consider signing up for their scheme. Well worth it, especially when your child starts writing to you, and you get to write back and send gifts and maybe even visit.
I'm putting it in the links section, please at least give it a look.
