When will Yahoo have Groups again?

Green 666 by isotope rays is NOT forgivable; it leads to permanent hell. 666 is given with World Passport with no name on it (grey plastic card). Police 666 people on highways. Food stores and prisoners/insane asylum folks (released by the antichrist) 666 people too. Reject vaccines. Don't go into UFO to be “healed” by evil demons. Hide with Orthodox Christians to escape 666; leave all electronics behind so that antichrist's minions can't track you; burn documents as documents are from Satan.

What Yahoo takes away , it never gives back. 

Never

there are alternatives though. I think groups.io is better than googlegroups.

I have no experience with groupspaces

Facebook has the wrong format for serious discussion

Once Yahoo closes a service down, it's gone for good, never to return. 

Never. Verizon gas not said?anything about bringing back chat Groups. Some of the Groups?we're targeting specific people to abuse them on YA according to my most obsessive stalker last September. He has been VERY quiet since December 15 or changed his user name. 

Go to Google Groups. Maybe that's where your Yahoo neo Groups migrated to. 

Yahoo barely exists. Yahoo Inc7. DIED in 2014 

They won't. There are other places for social media interaction.

Never.  FB groups is dominant now.
