I didn't know we did, until this thread. The notice on the website doesn't say, and (as an individual member) I haven't had any emails. But is there a deadline for nominations? Looking at the Constitution, the deadline for "matters to be raised at a General Meeting of the Association, including all proposals for constitutional change" is 84 days before the AGM, which was 19th March (yesterday). I can see nothing in the Constitution about a deadline for nominations, and since the Constitution itself says that one of the purposes of the AGM is to elect officers, that's not a "matter to be raised".
The Manual of Operations says "Deadline for receipt of nominations for Executive, Officer (Standing Committee Convenors) and Club/Individual Representative posts by Secretary, as well as any items or proposals to be raised at the AGM" is "Midnight on Day of Council Meeting Preceding AGM" and "This is a Constitutional requirement" - I can't find anything about that in the Constitution, which also says only that Council shall meet twice per year, and not when (so it could, constitutionally, meet the day before the AGM).
