Yes, it’s a closed group with an obfuscated name. Apply and you will (hopefully) be let in if you sign up for Meetup and pass the “I am not a troll” survey test when you join. If you’re having trouble or for whatever reason you want to contact me personally, see my own site at http://howtosee2020.com — I was thinking about setting up my own forum there but so far all I have is an email alias. So far it’s just me at the other end!
