We just decided to cancel the ARC (hopefully hold it over until next year).
Sounds like a good choice for your sanity - you don't need the last minute drama that would no doubt accompany it and I think we were all expecting it more or less.
definitely the best choice for the sanity of the organisers. there's enough other chaos at the moment with everything that's happening with work and schools. and I can't see that anyone would be booking any travel at the moment.
