Howdy, I got an email from the creators/maintainers of this list which said in various places it was the musicians list, organizers list, and upon second reading, also contra callers list! Wow! I'm going by the actual name, which is organizers. So.... organizers: If your group has a special, regularly occurring dance (for example a monthly dance on a weekend when most of your dances are weekly on a weekday), do you have specific criteria for which of your regular callers is eligible for calling a special night? If so, what is that criteria? If you reply, it would help if you also tell me which dance community norms you speak of. Our community (Cincinnati Contra Dance) is looking into this question. Thank you! Liz Burkhart
