No, the June Journal hasn’t yet been published.
I am not directly involved with the Journal, though I’ve seen an email about the preparatory work that goes on behind the scenes, that means it should be very soon. The way to tell is the most recent Journal on the homepage is still April. Once it is published the Newsletter will be emailed. This is timed to be close in time to the hard copy arriving with members who subscribe to the paper version.
