WIKI experience

1.  Teflpedia

2. Richard Doyle, English Fifteen in 15 Weeks! 

This course will teach instructors new to Penn State's Composition program how to teach English 15, the introductory rhetoric course required of all Penn Stategraduates.

3. Wikiversity, a Wikipedia-Like Learning Community

Wikiversity is a Wikimedia Foundation project devoted to learning resources, learning projects, and research for use in all levels, types, and styles of education from pre-school to university, including professional training and informal learning.

To sum up, I want to  point out that these wiki services are  completely new for me. I need some time to study them , but I am sure they are quite simple and still effective.
