I came across this site via Nik Peachey and was planning to try it out. Next week, I´ll be talking about films with two groups of mine and decided to use http://wallwisher.com to have my students recommend films to the group.
Anyone can join us in our WALL by clicking on post a sticky and then double click with the mouse, write a description of the film and add the link to a youtube trailer. This is our FAVOURITE FILMS wallwisher.
Nik Peachey has also started a great wall about WEB TOOLS for teachers:
This is Nik´s wonderful post about WALLWISHER
