Yes, I joined them, and they are pretty welcoming.
What really helped is when I tried posting on the Facebook Escapees group asking if any Golden Nugget chapter members were there, as I had a few questions, a couple of them replied right away, and sent me details by email.
I think that on every chapter pop-up on the Escapees site, there should be a link to a central "anyone can post" place (like the FB group, or maybe here) where chapters and BOFs and their members can exchange information, announce meetings and rallies, etc. I didn't spend all day looking at all the chapters, but I found most just list officer's email addresses, and others might have a web page that hasn't been updated in a long time or is kaput ... even if it's been updated recently, members or prospective members usually can't post to a blog.
