I’ve put up a registration page for wherecamp 2012. It’s right before Where 2.0 on the 31 March & the 1st April (which also happens to be the OSM license change deadline). Details like venue are still being worked out. It’s free to attend (but donations welcome) and people like you publicize the event so we can get awesome sponsors to pay for things like food. Also, feel free to get in touch if you’re so inclined.
