I believe on Quaintasses application form they ask for your gender identity there is a box on the list for not assigned.
Thornbird,
On some CBA application forms, it has a list of six or so, the last one is "Prefer not to answer", how would you handle that for CASA at ~$10,800 a time, seeing as it is fully approved by the AHRC.
As harmonisation is all the go these days, CASA could harmonise with Transport Canada, which, as directed by overarching national legislation, has to recognise (as I recall) 23 genders, and in the best of CASA tradition, getting it wrong is a criminal offense.
Tootle pip!!
