I've been to some conventions for an online flight sim. I have never met anyone that I would not invite home for a BBQ.
I have traveled around the USA on business and scheduled time to meet for dinner or lunch with some of these people. It's the ones that don't get out and mingle that I'd worry about
I live 8 miles (20 minutes) from Portland International Raceway. There is a book out on the history of racing in the Pacific Northwest titled "Long Straights and Hairpin Turns" by Martin Rudow. His father raced against mine in the late 50's and early 60's. Even had the same (almost) car. My dad had a Veloce version of the 1958 Alfa Romea Gulietta Spider. I met him at this year's Historic Races at PIR.
Even though he doesn't do any simulated racing, I'd even invite him home for a BBQ
