=== Caveats ===

Some output, particularly involving user-supplied inline HTML, may not
produce 100% valid or well-formed XHTML output. Testers are welcome to
set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
cases, but this is not recommended on live sites. (This must be set for
MathML to display properly in Mozilla.)

A MediaWiki-l mailing list has been set up distinct from the Wikipedia
wikitech-l list:

  http://mail.wikipedia.org/mailman/listinfo/mediawiki-l

A low-traffic announcements-only list is also available:
  http://mail.wikipedia.org/mailman/listinfo/mediawiki-announce

It's highly recommended that you sign up for one of these lists if you're
going to run a public MediaWiki, so you can be notified of security fixes.
