History+Tab+Practice

Each time some edits a page, a wiki saves the changes that user made. Every version of every page is kept to make it easy for members to revert back to a previous copy. You'll never have to worry about losing changes or being stuck with a new bad version of a page if someone makes a mistake.

Thanks for approving my membership so I can complete my weekly assignment for class. I saw on the discussion board that you want to work on your wiki and blog over the summer. . .good idea!

Perhaps we will have some time to work in our classrooms at the end of the school year that will allow us to collaborate on the use and integration of our blogs and wikis. . .in a perfect world.
