Hi,
the another big question is that why don't include JQuery to load
automatically with _every_ pages? Now at least two wikis load JQuery
v1.3.2 from common.js (see
http://zh.wikipedia.org/wiki/MediaWiki:Common.js,
http://hu.wikipedia.org/wiki/MediaWiki:Common.js), the
UsabilityInitiative extension use JQuery v1.3.2 with cookie and
browser plugins, and the collection extension use JQuery v1.3.2. Three
JQuery, two version. This is not goooood...
Farewell,
Glanthor
