[Air-L] alternatives to closed, secret Facebook groups?

[Charles M. Ess]

Dear AoIRists,

I hope this finds you well, despite it all.

I'm wanting to know if any of you have good experience and can thereby 
recommend alternatives to a Facebook closed or secret group - i.e., a 
platform that offers the functionalities of these, but avoids 
entanglement with FB?

Yes, I have some realization that, to put it in Montanan, there ain't 
nothin' pure, especially in the online world.  But there are greater and 
lesser degrees of entangelement, and these may be relevant to the 
project I have in mind.

Many thanks in advance for any advice and suggestions you can share.

best,
- charles ess
