1.) What church do you attend?
A Unitarian Universalist church in the next town. About 150 members, middle-sized for a UU church. Very friendly, smart, compassionate. Some of us are a little neurotic but it doesn't stop us from doing good and having fun with it!
2.) How did you decide?
Realized I wasn't strong enough to be an atheist when it was time to DA. Promised myself I'd DA as soon as I could find a church that didn't require me to believe a lot of bullshit, especially not hellfire, the trinity, the immortal soul, or knee-jerk political conservatism. Thought UU might fit the bill, and http://www.uua.org showed I was right.
3.) What is required of you as a member?
Be kind, be honest, live, love, laugh. Encourage the people around you to do the same.
4.) Do you believe in all of the teachings? Do you have to?
There's a shortlist of ethical principles that are damn near non-negotiable. Belief in God is not one of them.

The denomination has an adult-education course called "Building Your Own Theology," which is precisely that. It's all about discovering exactly what you DO believe, and why -- in company with a group of friendly people who probably believe way different stuff. When I took it, the atheists in the room were fascinated by us pagans, and very sweet about it.
I believe in all the "Seven Principles" of our church. I don't believe in all the "Six Sources of our Living Tradition" -- the Bible, especially; and though I trust it, I'm not very good at "Humanist teachings which counsel us to heed the guidance of reason and the results of science." I'm something of a magical thinker, though I take that with a grain of salt, too.
I didn't mean to evangelize so much, but no two UU's believe quite the same (nor are they expected to), so I thought I'd better give my personal take on it.
Before I forget: going to church "for social reasons" is a perfectly legitimate thing to do, especially if you have kids. Many UU churches do "the social thing" very well. Even if you decide it's not for you, they won't hold any grudges or shun you if you leave. It's part of that "drawing from many sources" thing.
