FWIW, it would probably be better to just transfer the group. The transfer establishes everyone’s Groups.io account as well as membership in the group, and copies their subscription settings (Individual, NoEmail, etc.) as well. Their account will initially have no password, unless they are already a Groups.io member. Each individual will begin receiving messages and can post or reply by email immediately upon transfer regardless of membership.
If they wish to visit the group’s website for photos, files, etc., they will need to create a password to be full members. That is a very easy process the first time they try to logon.
And, unlike Yahoo and the other big services, they won’t have to give up an appendage and their first born.
Memberships are transferred first, followed by files, photos, and so on. When finished Groups.io will send a message to each individual letting them know they are member of the new group along with appropriate links. Once that is done, I would suggest switching everyone’s membership on this group to Moderate and perhaps post a message saying we’ve moved and pointing them to the new group home. Hope this helps!
