Do you know hp calculators communities on social knowledge sharing sites?

[Pier Aiello]

As the title says, do you know other communities about Hp calculators (maybe general communities are easier to be found) on Reddit, Quora, stack exchange or other social knowledge sharing sites?

After a quick search i found only: this subreddit

There's a small but growing "HP Calculator Fan Club" on Facebook:
https://www.facebook.com/groups/hpcalculatorclub/

(If posting the above is against protocol here, just let me know, and I'll delete it.)
