The guy who runs groups.io is the one who created onelist, which became
e-groups, with got swallowed up by Yahoo!, and then he left.
He knows how to do it. People who have switched over seem happy with
it.
BUT, does he have an appropriate level of resources to handle THAT much
traffic?
I saw a posting about this on one of the groups I am in (XXCopy) and it
seems as if groups.io is not free. At least there was talk of a $110
payment.
