I’m on FB at https://www.facebook.com/geoffrey.m.arnold  but I’m restricting my activity there to a few groups, plus old friends and family.
I’m no longer on X/Twitter.
I’m ramping up my activity on Bluesky, and I hope you’ll join me there.
I no longer monitor my LinkedIn at  https://www.linkedin.com/in/geoffarnold
