Oct 9th.  The latest issue of Daltoniana (#124) has just been emailed out to to all who requested it via your GDPR permissions.  If you haven't received a copy, please send a message via the contact page.  Daltoniana issues 1-123 are available from this website for download.

Dear Andre, Barry and Jay

We missed you in Ljubljana.  We recorded a very amateurish video to say 'hi' from the business meeting.  It started recording just as John was talking about you, Andre, and how this is the first IRGCVD/ICVS that you have not attended.  And, Barry and Jay, we wanted to send you both our best too.  We hope all three of you are now in better health.

Although this is on the website, it is only visible to people I've sent the link to (i.e. the 3 of you).  It was too big to email!  You'll need to download it so right click on the link below and use "save as" or whatever the Apple equivalent is!  Email me (This email address is being protected from spambots. You need JavaScript enabled to view it.) when you've got the video and I'll take it down.  Sorry about the poor video quality and the terrible sound!  It's the thought that counts!

With best wishes.
