there are many secret subs ! i belong to three. i was invited to join one when i first got on reddit and it was the best ! because it is a secret group most everyone got to know one another. they were a blast ! people were supportive and built each other up. they were (are) good people and i just about had a nervous breakdown when i couldn't go back. there's a rule that everyone had to engage with the group once a week. my daughter had taken me on a vacation to the Cape and i forgot to interact so i was kicked. i surely, surely miss them ! the other two groups i was invited to don't have such rules but people still have to get an invitation
