There's been calls for footnotes [[m:Footnotes]], and it is an ability that I've wanted for my own wiki for a while, so I hacked up some changes to Parser.php and Skin.php (from CVS about three weeks ago). I used the formatHeading function as a template and I am not even a PHP novice, but the code works okay.

I used [note:foo] as the syntax. There are, I'm sure better choices.

Known issues * When you have section editing turned on, you can click on editing the Notes section. You shouldn't be able to do that because there is nothing really there. * Double quotes in the note break the hovering behavior of the in text reference

Thanks for MediaWiki!
