If+more+than+1+person+edits+the+page+at+the+same+time

=The following explains what happens when more than one person is editing the same page at the same time:=

I clicked the edit button and I received a "Draft Recovered" notification. What does this mean?
This notice comes up if, the last time you were editing the page a draft was saved but you did not save the page. If you "Load Previous Draft" you will load the last draft of these unsaved changes and begin editing from there. If you "Discard Previous Draft," you will begin editing the last saved version of the page.

What is the "Save Draft" button at the bottom of the editor?
This button will save a draft of the page. If you leave the page without saving, the next time you edit the page you will have the option to load that draft or discard it. We save drafts of your page automatically, so if your browser crashes or you accidentally "Cancel" your editing, you will be able to pull up that draft again. Note: You shouldn't think of saving a draft of your wiki page as the same as saving a document. If you click "Save Draft" and then "Cancel," this draft will only be available until the page is edited the next time. Saved drafts do not appear in the history of the page.
