Elke Dieterich, a german woman I met in Zanzibar. she is a manager without borders, after joining Manager Ohnegrenzen. She took time of her career as Marketing manager in Germany to be a volunteer in Tanzania for three months.
Her blog is elke-dieterich.de, in German language, but you can read it in English, with little help of Google Translator tool.
I am still enjoying my vication in Tanzania - East Africa.
