I have started a podcast about doing these projects! It's a new media to me so I'm still figuring out a lot about all aspects of it from technical recording issues to hosting issues, but you should be able to listen to it here and presumably maybe from there if you are a regular podcast listening download it for later listening as one does. It's all very new to me. Anyway, so far there's an introduction and two episodes about Nigeria. It looks like they're queued up on that webpage in kind of an odd order, again, lots of things to work out! The idea is to update once a month.
And once more big link here to the podcast!
