Will they also be going through dinners, office-hours and the like?

I could see this being a good way to help new non-profits get over the initial hump of raising awareness, getting administrative issues sorted out and so on. Certainly a service worth more than just the money provided.

Yes, everything is the same. They're going to present at Demo Day too (lots of rich people in that room).

That is awesome. A really great use of the YC network.

Site and mission sound great, I'm looking forward to contributing.

Hopefully it'll quickly join the ranks of the larger crowdfunding non-for-profits like Kiva.org, Donorschoose, etc...
