I have pushed a little for this event earlier (in a private log) but have now been asked to remind and inform my North American friends of its existence.
WOD is a world wide promotional event to be held on May 11th - at present with organizers registered in 41 countries. The interest from USA and Canada has been low so far (one US entry, Canada zero) so it´s time to start planning - don't let this opportunity slip out of your hands.
Lots of information, folders, posters and other promotional material can be found at:
