This is a truly awesome resource - thanks for sharing that! I'll be getting the retro computing crew, that is forming around our new exhibit at the Retro Gaming Museum, excited about this!
Who knows, maybe we will have a retro- net up and running in the next few days ..
Go for it! These communities are pretty active so you can also join one of their events.
Definitely going to try to attend the next one .. thanks for the heads up!
