Test:
I'm sad that it seems like the suggestion by our dear departing fantastic_mrs_fox@85 didn't achieve critical mass. But I didn't want to just give up and lose track of those departing.

So in hopes of either modelling a solution or sparking any other solution, I have implemented my suggestion @89 to create an (email) mailing list. I did so on Google Groups, but note that one does not need a google account to use a google groups mailing list. (Though @100 I provided some links advising how to create, and lock down the privacy settings, of a Gmail account.)

A mailing list works simply: it comes to your email Inbox, and you sent email to it that all subscribers get.

Obviously I think the mailing list should be run by someone everyone likes, such as fantastic_mrs_fox for example. I consider I.T. a sacred trust, and am trustworthy, so I am happy to have or to /not/ have any role that is desired (for example, I would be very happy to completely turn over all administration of and permissions on the list).

The name can always be changed, but the name "The Savage Lounge" is it's interim name.

I have made it:
So Join requests must be approved by the Admin(s).
So only Members can see and participate in the discussion.
So only the Admin(s) can see the member list.

Subscribing to The Savage Lounge

To subscribe, if you have a Google account you wish to use, go to https://groups.google.com/g/savage-lounge and click on "Ask to join group". (If you're not offered "Ask to join group" but are offered "For access, try logging in" click that to log in to Google, after which you should see "Ask to join group").

If you don't already have a Google account you want to use, you can create one (free) at https://accounts.google.com/signup?hl=en
Note that the account creation screen defaults to having you create a new Gmail account, but you can click on "Use my current email address instead" which creates a new Google account associated with your existing non-gmail email address.

If you want to subscribe to The Savage Lounge but also want to /not/ use a Google account (which means you will receive emails but won't be able to use the Web interface to the The Savage Lounge), please send an email to savage-lounge+managers@googlegroups.com with a Subject Line like "Savage Lounge Subscribe Request" from the email address you wish to subscribe.

Unsubscribing from The Savage Lounge

Send a (blank) email to savage-lounge+unsubscribe@googlegroups.com
You don't have to remember this unsubscribe address because it appears at the bottom of every post from The Savage Lounge. Unsubscribing from The Savage Lounge means you will stop receiving The Savage Lounge emails and will lose Web access to it.

It is possible to make it impossible to find without the link, but then the /only/ way to join would be by emailing the Admin.

Other privacy options are available (and could be discussed by those who join or want to):
1) It can be restricted to "Adults Only"; and maybe we should, I don't know.
2) Emails to the mailing list can appear to only be from the Group (which I think means we'd have no idea who sent them); seems to me that this kinda spoils the idea of extending the community.

You might want to avoid making a YahooMail account, since they've had many breaches.
