Comments about Privacy/Openness

I see the "please comment here" suggestion, so here's a new thread for comments. (Moderator, please advise if I misunderstood!)
I personally feel comfortable with the level of privacy set up so far. I think it is sufficient as is for us to announce meeting places, and allow kids to chat, with the same feeling of confidence that I'd have at a homeschool gathering where I didn't know everyone well. Just my two cents.
