As they are free, I would suggest that such people acquire one. A Gmail address works. Otherwise, such people can wait until we're finished collecting the data and migrate to a wikipage. Google spreadsheets export to a number of different formats including .cvs, .html, and .xls, so it's not too hard to migrate. For this sort of thing, having a collaborative edition while getting ramped up makes things much easier. Cheers, Bijan.
