Who assigns moderators to the various Community groups?
I have found responses to be sadly lacking in at least one of the groups of which I am a member, viz. https://community.familysearch.org/en/group/65-familysearch-family-tree. My suggestion has been to wind-up little-used groups, especially - as in this case - where there is a suitable alternative within the main body of Community.
Perhaps a Community administrator would like to examine the activity (or distinct lack of such) in many of the groups and - if they are to be retained - ensure there is a moderator available to pay frequent visits in order to address queries that are currently being left unanswered.
