Online classes in travel and tourism

I'm really excited to share an online course that I teach, offered through Village Earth and Duke University, called Tourism and Development. It's part of a larger certification program in Sustainable Community Development. I'm also excited to see that there are several other tourism-centric online courses and educations springing up for tourism professionals all over the world, such as

Certificate in Sustainable Tourism Management by the International Ecotourism Society

Like most of us here on Outbounding, I work in the media and communications area of the travel industry, so I do a lot of writing. An academic background in tourism has been invaluable in informing my writing. 

My question is - does anybody know of any online courses more directed specifically toward travel writing, editing and publishing? What kind of formal training have your travel writing peers and heroes pursued?
