Thanks, Shal, for the clear and helpful reply!
Not trying to game the system. Just wanted to be sure that I had not missed such a feature when going through the excellent Owners Manual. (I was concerned because -- when I searched on subgroups -- some of the key info turned out to be located in wiki entries rather than in the Owners Manual.)
I got the pre-authorization idea because, at one point the now-living-dead LinkedIn Groups system had pre-authorization, which worked quite nicely.
We will switch to the Premium level. First, in fairness to Mark.?
And we want subgroups.?(We have a website, so we don't need calendar, database, photos, files, or wiki. Our members are not into chat. Unlike many other groups, we've found that an archive of old posts is not very useful for us due to the continually-changing info. Polls would be useful. We have Eventbrite for donations, which works very well.)?
In short, we need an email-based, moderated discussion system with reliable email delivery.
Agree about spamtraps. Given the care our team has taken in vetting applications over the 20 years, we would only have a spamtrap if a legit account has been taken over.
Agree on people marking invitations as spam. Given the varying level of email literacy -- and that many are set to "no email" -- there will be people who do this.?
Deliverability is the Achilles heel for any email-based system.?
For example,?Gmail, marks confirmation emails from Yahoo Groups as spam -- and the spam folder is hidden. Our directions say: "If you don't see the confirmation emails within an hour, check your Spam or Trash folder. (In Gmail, click "More" in the left-hand menu to find the hidden Spam folder.)"
My bet is that, as Groups.io grows in membership and volume, Gmail will do the same with Groups.io's confirmation emails.
Thanks again,
