Are there “chat rooms” or discussion lists for people interested in PCP?
We don’t know of any chat rooms but there are several discussion lists that people interested in PCP can join. The general Mailing list maintained by the British ‘jiscmail’ service, a specific research-oriented list called PCPtools (also at jiscmail), and a list maintained by the people who run the ‘Enquire Within” web site (connected to the Repgrid analysis programme of that name).
