Adelante Africa is a great fit - we'd love you to post to Solvers and we'll try to put some eyes on the project.
Just this morning I heard that a Solver had helped fix the website of another Africa-related charity, TReND in Africa. We're still in open beta and would love feedback.
It comes up with 'Uh-oh couldn't find that page' and then loads after a few seconds whenever I middle click a project to open a new tab.
Also when I click a project on the home page it doesn't reset the scroll position, so for many projects I'm left looking at a bunch of tags.
It also looks like it presents a completely blank page when js is turned off, even if I pretend to be a google bot in my UA string, which means you'll probably be screwed for SEO.

My advice, don't try and make a Single Page App when a simple website would have sufficed. The tech available to us at the moment just doesn't support it.
We're already quite far down the single page app route. It does have some drawbacks, but has also allowed us to develop pretty fast and enables some planned features that are hard with simple websites. There are solutions for the SEO thing - but none that I know of for people with JS turned off.
