Hi Lifeisfun
I'm new here as well. I just registered recently but have been reading for about 5 years.
I'm a convert and have always had a network of friends outside the congregation.
I've always got some project or interest going on and I find that I meet new people through those ways. At the moment, I'm trying to teach myself how to play golf. I can't putt straight to save my life, so to speak. The other players at the driving range notice this and the conversations arise from there. People love to talk about themselves and their interests, so I ask them things like "how long have you been playing? What do you like about the game? Etc, Etc, Etc" The conversations go from there. (I don't ask personal questions and just keep the conversation about golf and the weather and so forth.)
You have the social skills and as has already been mentioned, you made friends in the congregation, so you just use those same social skills out in the community.
