Nick: Some good stuff in those links - thank you.
Donna: I love the idea of identifying your role by saying "boy" or "girl". Thanks for the link to your web pages. I did try to look at your FB group but got a "this content isn't available right now" error message.
Neal: I'm intrigued by the "not wearing bands/physical identifiers", and more so by mid-tip role swapping. How does the caller cope? If xe is purely using modules then there's no problem, but how does xe cope if xe is sight calling? OK xe could memorise 4 positions rather than just two couples, but if the dancers are role swapping xe may not be able to tell what FASR the square is in.
In my MWSD classes I insist that the "boys" wear a sash and the "girls" don't - irrespective of actual gender. This is partly to make it easier to see when the square has gone asymmetric, and partly to eliminate the idea that "boy is the natural role of a man, so if a woman dances it she must be marked out in some way (and vice versa)".
