Maybe Balisage is an XML conference (Goggle and Yahoo both seem to let you find it that way). Maybe it is a Markup Conference (but the big search engines don't exactly know what that means...)

Whichever or whatever, if you are coming, do a poster.
POSTERS can add a lot to a conference; add your thoughts
to Balisage!
