[Mediawiki-l] RSS for any given MediaWiki page

[michael]

I have seen that there's RSS (etc) feeds under Special:Recentchanges but
if I want to be able to get an RSS feed for a given page (say
User:Michael) what do I need to do? 

And if I want to allow users to get an RSS feed for any page, eg by
clicking on an icon, is there an efficient manner to set this up?

Sorry if this has been answered before but I'm new to Wiki management
and my searches have proved fruitless.
