Wiki's

i am looking forward to setting up a wiki for my students to post their work so their parents can see their work and the others in the class. I know the parents would like to see their own kids work but it would also be nice to see how their child's work compares to the others in class. This way, we might avoid the uncomfortable question from the parents " Why does my little Johnny have such a bad grade. he does all the work. He says you don't like him. What is going on? Those are always such fun conversations.
