A WikiBadge is a page intended to be linked on other pages for the
purpose of marking them in some way. Eg Delete Me, Rename Me, Hot
Topic.  To mark a page, add the desired WikiBadge as a link, usually
at the very bottom.  If you want to discuss a badge but don't want to
mark the page with it, insert a space so that it will not be matched.

The badge page may describe itself more fully if needed.
Also, because of BackLinks, if you click the badge page's title you 
will see a list of all pages marked with that badge.

For example, this page is itself a badge marking all the WikiBadge(s)
in use on this wiki. Click the title above to see a list. Also, MarkedPages combines such lists onto a single page.

Warning: see WikiWikiWeb:WikiBadge for more info, including discussion
of why they can be a bad idea.
