We will have a Boston contingent. It would be good lay plans and coordinate travel and, if appropriate, posters.
There's talk of a Wiki Train -- reserving a whole Acela car for us and the NYC contingent, which the Wikimania organizers would partly subsidize.
So, roll call: are you planning on attending? Would you be interested in taking the train?
(yes and YES!) -SJ.
