Yes, find a meeting on our meeting list, and then just show up. You don't have to talk, there's no signing in, it doesn't cost anything. If it's your first time going to a meeting, you just walk in to the meeting, pick somewhere to sit, and that's all you have to do.
If asked to introduce yourself, just say your first name, and that either you are "just checking it out" or "this is my first meeting" or "I'm an alchoholic"- whatever you are comfortable with.
