I still post on The Knot newlywed boards, and on occasion the new Nest - which I don't care for much.
I also am a member of a small community of women, we met on another message board years ago, and created our own - we talk about ethical issues, health concerns, empowering women, and just treat each other like sisters. They are all very very good friends, and I've met several of them already =) And because it's password protected and you have to apply for membership, we have no trolls and no cruel fights.
And then here =)
