Jack of Oz is currently, or is about to be, on vacation in real life from 11 December 2014 until 10 January 2015 and may not be able to respond immediately to queries. He may pop in now and then from an available online source.
This is to remind me that:
♦ my or anyone's individual contributions to this project are drops in the ocean, but
♦ the ripple effect of just one drop is unknowable and unstoppable, and
♦ without all those drops, there would be no ocean and no ripples.
