I set up a wiki a month about teaching and a half ago as a way of familiarising myself with the tool as I don't use the blog too much. http://howadultslearn.wikispaces.com/ There I have developed a piece of text that i started a while ago here in blogger about how adults learn English according to my experience, then I went on putting info about what i think are good ways to improve the students listening skills as well as speaking and other ideas and experiences from my teaching.
