Thank you all
For reference, I am white, have short, asymmetric, dark hair (I don't have a photo to hand which is representative of my current appearance) and I was in the Saturday Fun and Games session, Queering Shakespeare, and assisted with the programming workshop. I also ended up playing rather a lot of bridge with mattp and others. I also wandered around in a red shirt, bow tie and top hat towards Saturday evening.
This has been a good weekend. Thank you.
