I think what people are trying to say is,
if there were meet and greets, people don't discuss it in an open forum for security reasons. The event Lexus held at her home was her own deal and I believe she posted the invite in coed. Most don't do that, but we all have our own level of comfort.
Just hobby along, get involved on the board, and eventually you could possibly run into someone who knows someone who knows someone who *might* know about an event. But generally speaking, you never discuss in the open. It would be an exercise in futility anyway, because meet and greets don't exist! Like Raven stated, First rule of Fight Club is there is no Fight Club.
I disagree that it has anything to do with post counts, board presence, or reviews. It has more to do with who you know, IMO.
Hope that helps some
