A Yahoo group owner can export a membership list to a csv/tsv file for up to 1,000 members. An extremely ambitious person could cut, paste and reformat if the membership list had over 1,000 users.
An ambitious person could do an invite to a new Groups.io group using that list. Would the group transfer still work thereafter, but skipping the membership transfer part?
Assuming it works at all, would it provide linkages between email addresses and posts? What about the member's starting date? Would that be from the Yahoo membership list or from the date of the Groups.io invitation?
