Deleting a page
Admin users can delete pages.To delete a page, browse to the page and add /delete to the end of the URL.
For example, if I wanted to delete a page named UselessPage, I would browse to the page, click in my web browser's address textbox using the mouse, placing the cursor at the end of the address, and then type in /delete and hit the Enter key on my keyboard.
So the address would change from:
http://docs.wikkawiki.org/UselessPage
to
http://docs.wikkawiki.org/UselessPage/delete
