I am a member, although I am not very active, I think I can answer your questions. Everyone who has any interest in brewing is welcome, no matter the skill level! Just introduce yourself as someone new, and you will be tasting some homebrew in no time. I found the vast majority of people to just be beer geeks who wanted to talk about and share their brews.

Do not at all be afraid to go to a meeting. It is a pretty diverse crowd with respect to personalities, from introverted to extroverted, but tends to attract college to middle aged men (there are definitely women brewers at every meeting).

We have been meeting at the Red Mile, but I think that is going to be changing with Beerworks and Country Boy Brewing opening. I would say keep an eye on the website, but I don't think it gets updated regularly. I will try and drop you a line when they decide where the next meeting will be.
