Don't I recall that CC0 is the only CC license that isn't a problem?

BY - is attribution on the Contributors page good enough? Nobody knows,
so we ask for specific clearance.
SA - ODBL doesn't require SA for certain derivative works.
ND - Totally unacceptable for a database open for all to edit..
NC - We do not restrict the field of endeavour of our users.
