Hi Gene,
Welcome aboard.
I enjoyed reading your OP. It reminded me of the time I joined this Forum.
Like you, I was not into social media. In fact, I had zero involvement with social media, on line forums and the like, except for doing a little Facebook.
Unlike you, I joined this Forum almost immediately after I found out about it, from one of our fearless leaders, Alan Arnold, back in November 2017, and I have been one of the most active Forum members ever since.
For me, this Forum is a great a source for knowledge and information about our great hobby and wonderful trains, comraderie, a place to express one's creativity, and entertainment.
You should derive many of the same benefits that I have as a Forum member.
Except for my heavy involvement here, a little bit of involvement on Facebook, and occasional involvement with LinkedIn for my profession, I don't do any other social media.
Again, Gene, welcome aboard. Arnold
