The Yahoo Groups platform is shutting down. No, not yahoo.com nor yahoo mail but rather the Group functionality.
To many this will be a non-event. To others who belong to or use a Yahoo Groups Forum it is 'an event'.
One such Forum on Yahoo Groups is the CIVIL_SMA Forum, similar to this Forum but 'all about' San Miguel de Allende. It's been announced that this Forum will be moving 'soon' to another 'groups platform' called groups.io.
If you are a member of the CIVIL_SMA group you should be getting an email 'soon' announcing the change.
