What happens when two or more people edit a page at the same time?
If you and other users are editing at the same time, you will get a small notification window, letting you know who else is active. The system will allow concurrent editing, but will only save the LAST page saved. If you and Brad are working on the same page, and you save your changes before Brad, his page will overwrite yours. Your changes can be found under the history tab — you can load your page, and cut-and-paste your changes into the new page.
