Remember! Although wikis allow for asynchronous collaboration, if two people try to edit a page at the same time, the system won't know which one to save and you could lose information.
When adding a new page, always make sure you are on the page that you want to create a subpage within. For example, if you want a 6th grade subpage, click on 6th grade, then select "add a new page" from the Page Toolbox.
One of coolest things about wikis is that you can restore the history. If you accidentally change a page or erase something, you can restore it. See the blue box below - click "complete history" to see what I'm talking about.
If you delete a page, you will not be able to create a new page later with the same name.
