Each time a Page is saved the previous revision is kept in an archive. This means that all the changes are visible through the History button at the top of each Page.

The table of changes contains the date and time the update occurred, who made the changes, what their IP address (network address) was and how different the Page is from it’s previous version.

To compare revisions it’s simply a case of selecting two different versions (Steps 1 & 2) with the radio buttons and then click the “Compare Revisions” button (Step 3).

A new screen will show highlighted changes between the two.

By viewing what changes were made it is possible to roll back any incorrect information or remove spam. See Spam and Graffiti for more info on controlling unwanted changes.
