Dear all,
I've uploaded my Wikimania slides, and I created the category on Commons
"Wikisource presentation slides":
http://commons.wikimedia.org/wiki/Category:Wikisource_presentation_slides
Please use it in the future, and possible on your past uploaded slides, it
would be nice to have them all in the same category.
We have a lot work to do together, let's start sharing our documentation :-)
Aubrey
