Quoting Russ Abbott, from the post of Mon, 11 Jul:
Hi,
As a new wiki user, I have what may be a trivial question. Is there any way
to set things up so that users can elect to be notified when selected pages
change?
not with the plain-vanilla MediaWiki, sadly, but there's an excellent
extension of it, and it is kept closely up-to-date with the main
product:
