Breastfeeding support group - how do they work?

Shema N

On another thread someone suggested I visit a breastfeeding support group in my area which I plan on doing.

I know this sounds like a weird question, but what happens at these support groups? I'm assuming it's a very supportive environment and women share their issues, practice latching techniques etc with the LCs at the group? Should I buy some kind of cover or is it OK to go topless? I want to observe proper etiquette!
