@uwiikz-- I too was involved in several different Internet chat groups, reflecting an array of interests. From them, I actually made a few friends in real life.
At its best, these boards serve a function beyond answering technical questions, or providing needed "how to" info -- there is a sense of shared community, a bond that exists among the members that goes beyond their common interest in a particular subject. There was a member here who recently passed away, and everyone said the same thing-- he was knowledgeable and never foolish, and never engaged in mud slinging. I think he was well loved because he was knowledgeable and always took the high road,
As to legal claims, the Internet and the like:
I am a lawyer- I practiced in NYC for 34+ years, specializing in copyright. I had a fair amount of involvement in the Internet early on in some of the foundational cases and beyond. I also helped a well-known board focused on Ferraris gratis because I liked the board and some of the folks who were regulars there- I will tell you there were some great people there, and some who were...well, not so great. It could be a mosh pit sometimes.
My best advice to you is simply to let it go and move on. Illegitimi non carborundum.
There is a dealer in NZ named Jason Parmenter who I haven't spoken with in years, but we shared some interest in the same gear.
