Its a shame, but if that is what you need to do ... *shrugs*
For my part programming has had to be relegated to just another tool; coding for its own sake no longer brings me the pleasure it once did. I am no longer active in the IT industry and most of my projects, these days, are based around microcontrollers using some variant of C (which I dislike, but not as much as I detest Java and Python).
What I did for the old Dragon group (retro system) when Yahoo Groups died, was open a free
groups.io email discussion group. It is free, available, and, with next to no traffic (a message per month), no problem adminning. I host the few files from the old group on DropBox.
Whilst not a forum, it does allow people to keep in touch when idiocies like Facebook fail, and it does keep the few active threads open for anyone who wants to chime in.
I'm still interested, by the way, in Script Basic - especially the SB64 version, even if I am still using Win7 and Server 2008R2 as my OS of choice.
Now, I'm going to head off to bed so that I can have some nostalgic nightmares about code-bashing on PDP-11
