Thank you for all this valuable information. I would very much appreciate any comments you may have about a volunteer program in Moshi, "Give a Heart to Africa." I believe they operate a school for adult women and offer a variety of courses. They welcome volunteers who are interested in teaching in their program. They offer room and board and charge a fee which seems "moderate."
Having the opinion of someone who has first-hand experience in Tanzania and an overview of the volunteer organizations is invaluable. Thanks.
