At my alanon meeting we start with reading the 12 steps then the 12 traditions, yes taking it in turns then a topic is picked from a jar and we talk about the topic but are always invited by the chair to talk about something else if we wish when it's our turn to talk. On the 3rd week of every month is a step session. I have only been to this one and one other one the other one I didn't like as it was everyone talking over each other!
I hope you find a group that fits for you.
