Erica Shumener and I co-organized a three-day conference on the metaphysics of quantity, which was held at NYU on the weekend of May 1st-3rd, 2015. It consisted of a mix of invited talks and anonymously reviewed papers, with a keynote address by Brent Mundy (Syracuse) (!).

Reading groups are awesome. In the event that I become involved in some reading group (either by organizing it or merely attending), I'll try to link it here and keep track of what we looked at.
