A history of all revisions is automatically retained in the MediaPortal Wiki.
To view all revsions of a page, just click on the Date link beside 'Page Last Modified' at the lower right of each page.
You may view a previous revision, or view the differences between revisions and then choose to revert to a previous revision.
There is no need to lock pages when editing. MindTouch supports conflict resolution, much like SVN, down to the word level. So if other users are editing the same page, changes will be merged. If there is a conflict you will receive a notice and be allowed to modify or resolve the conflict.
