Things I do other than teaching:
pctanzania.org--website I collaborate on for volunteers in Tanzania. Related to it, my hard drive is a mirror for a giant repository of the stuff volunteers have built up over the years because we are trying to have a formal library so it doesn't get lost with the two year turnover of volunteers.
zummtz.org--a website I built to assist some VSO volunteers with their secondary project. It's not really populated yet, but I did teach them how, set it up, get them a domain name, etc. It's not really my project and I know nothing about it so I can't exactly add the content myself.
Shika kwa Mouse project--related to Shika na Mikono, but for ICT. I wrote part of it.
Turning water into wine. I make wine in buckets in my kitchen. Sometimes I invite Tanzanians over and show them how. Sometimes I teach other volunteers who can teach other Tanzanians. It's a great income-generating activity: it's easy, it's cheap, people like it and are willing to pay for it, it's a way to store fruit in a hot climate and it's something to drink that's safe.
