Members and Subscribers is synonymous.
I think of and understand:
Subscribers: as people who have a subscribed email address, but do not have a Password, and can only receive and send messages to a Groups.io group.
Members: as Subscribers who do have a Password, and can access the Groups.io group website to access all available features.
If those aren¡¯t the correct names to refer to these two distinct levels of Groups.io participation, what are?
