Be sure to check the FAQ first. There is a F.A.Q. button at the top of every page.
Q. I am worried that all of the wiki content might get erased or changed by accident. How can I backup the files?
A. There are two ways:
1. For single pages you can just cut and paste from the edit screen to a text document on your own computer.
2. To make a backup of every page in the wiki go to the admin button at the top and click
Grab a .ZIP of your wiki. This downloads a zip folder with all of the wiki pages onto your computer.
3. To revert to a backup copy of a page just go to allpages (link at top)and select the version you would like to revert to.
