I'm running an event over on the Leica User Forum, details here:
In simple terms, it's a one photo, one day project, using Leica cameras and lenses on the 29th of February to capture your view of the day. So far, more than 150 Leica photographers have signed up worldwide. Charitable donations are encouraged (though not mandatory) to the Disabled Photographers Society http://www.disabledphotographers.co.uk/
Anyone from RFF with a Leica is welcome to participate.
