I have seen Wallwisher used in a few different ways by teachers, which has of course inspired me to write this post and come up with some more ideas of how to use it. So instead of writing the ideas in this post I have added them to the Wallwisher. Please feel free to add but additions are moderated.
If I was using this with students in real time I would not moderate it until later.
You do not have to set up an account, but for classroom use I would as you can save and view all of your walls.
Type in a title for your Wallwisher by clicking on Click here to edit title and do the same for the Subtitle.
When you have finished click on the 'done' button in the bottom right hand of the screen.
To add a note, double click on the wall, type in your note which is limited to 160 characters.
The notes can be moved around and organised.
The notes can only be edited or deleted by the wall owner.
If you have given a unique name to your wall, anybody can view and add to it http://www.wallwisher.com/wall/ineducation but in this case I am moderating the comments.
