pbwiki

I created a pbwiki and added some assignments to it. I can see that this might be better than using the student and staff share files. The students will have access at home. I like that. Additionally, it doesn't seem to cost anything unless you want upgrades of certain kinds? Is that correct? I like pbwiki because you can let only people you invite use it. It seems that when you add your invitees, you can select whether they have the right to edit or only read too.....yeah. If I am understanding it correctly, the students wouldn't be able to mess with the pages????
