I poked around the internet looking for a way to make a class wiki without much trouble.

It took a while, but I found PBwiki, which offer different levels of wiki service, but I have started with the free service. So far it is working out.

Learning the basics of wiki "code" is easy.

Once you sign up for a free account and create a wiki page (or two), you can give students access to it by sharing your adminstrator password with them.

If you want more control, you can pay for a wiki service that allows for separate passwords.
