Just a very brief post to recommend an option for anyone thinking of doing some volunteering sometime. http://www.hostelhoff.com is a website where you can find out about volunteering in Moshi in northern Tanzania, in the shadow of Mt. Kilimanjaro. The organisation is run by a friend of mine and offers a lovely hostel to stay in at a reasonable price, along with different volunteer projects you can work at for as long as it suits you. independent volunteering works out a hell of a lot cheaper than going with organisations such as i-to-i, which are really just businesses. I worked there in an orphanage last summer for a month and there isn't a single day when I don't think abou the kids there and how much I'd love to be back there having fun with them.
Tanzania is also a phenomenally beautiful country, with several brilliant safari options, such as the Serengeti National Park, sunkissed beaches at Zanzibar and Dar-es-Salaam, and of course, the surprisingly climbable Kilimanjaro. If you have alittle bit of time and money, and the inclination to do good things, look no further.
