TeresaQ,
>>> I realize Yahoo had "owners" while other forums tend to have "administrators"
It's the same thing really; a group Owner, or a group Moderator, are both group Administrators IT-wise as far as group management is concerned; it's jsut that the Owner is the ultimate group administrator (of any type) and has the ultimate group management authority.
And those are group IT structure/functionality titles, they have nothing to do with the group's purpose/organizational structure titles, so don't conflate the two, they don't have to be directly co-related to the organization's "board" functionality, they don't even have to be related at all; I mean, you can have a group owner who is just that, the group owner/admin, and still be nothing but a regular "member" as far as the "board" is concerned; they don't even have to be an "active" member/participant really;? I own and admin (along with other mods) 3 groups, and also I'm the (initial) owner on another group, on which there is another owner and a couple of mods, and I don't partake in the actual group discussions really (unless it is group-admin-related).? I'm just one of the owners because the group didn't have IT-knowledgeable folks back then and needed help to move from Yahoo, so I handled the group creation, migration. and setup on GIO, then just sit back and let htem run with it and only step in if needed.
Also keep in mind that as far as groups.io is concerned, while you can change an Owner to a Moderator, you still HAVE to have at least one group owner, so even if you wanted to "eliminate" that title from the group owner's account you wouldn't be able to.
