Some of you might have heard of this already, others maybe not, but I'm here to try and raise awareness.
ClinicCraft is a project being run by Dan Maher (MrPointyHead of Inside Xbox fame) and Chris Doney (of the M1ne Tube youtube channel) in support of Save The Children, raising awareness and money for the channel. The goal is to help raise the money for StC to construct 6 medical clinics in Liberia to support pregnant women, who currently cannot get access to aid and are forced to walk miles to reach it.
The ClinicCraft series follows the two as they construct their own medical clinic inside MineCraft, with all the facilities it would need in real life. They also encourage you to build your own, and not just to the same specifications - the most creative constructions will earn prizes for their work.
Remember that even if you can't donate (and even if you do), the goal will never be reached without spreading the word.
You can find their blueprints, as well as details for entering your own designs, and most importantly links to donate, at
http://www.cliniccraft.com/So I expect to see an entire neighborhood of clinics popping up on the servers soon
