If you are on BlueSky – @JohnnyOptimist.bsky.social, if you are on Twitter – NA (I no longer use that site), If you are on Instagram – @MacOlith if you are on FB, search for Mark Hellevang. I have many other social media where you can contact me if you’d like to converse / discuss / shoot the breeze, etc.
Those are really the best options, I rarely log into Instagram or FB, so please be patient if those are your primary sources. As I start listing more I will check those more frequently.
