I would be more than happy to provide an intro in that slot - I've done a
lot of similar presentations for education program events and for
editathons. I usually use
http://en.wikipedia.org/wiki/Wikipedia:CHEATSHEET as
my basic handout type thing; it can be printed out, but we can also just
give people the link (since presumably everyone will have a laptop with
them.) There are a few others floating around, but I think WP:CHEATSHEET
is the easiest/most compact to use.
I'll also try to come up with some possible topics and add them to the
editathon page within the next few days.
Thanks,
Kevin Gorman
