I woke up with two ideas for the conclusions chapter. One is that mail artists, including some on the web, are do-it-yourself art historians. TAM website and Geert's Mail-Art encyclopaedia are examples of intense efforts to organize and present the history of mail art. Artpool's massive collection of Ray Johnson's mail art is another example. Also, some mail artists use the web as an informal teaching tool. For example, Kiyotei made a rich instructional site on mailartist.com and Reine Shad provides all a teacher needs to integrate mail art into a curriculum for middle or high school including an example proposal to develop curriculum.
