I was one of the original users of Photometrica back in the day when Geir was developing it and think very highly of the program. However, I find navigating to VPHOT is obscure at best. You select VPHOT and it goes to a nice page that has two links, one to join AAVSO and the other to this forum.
How about putting a link to the actual program log in page. In fact, although I have found it in the past, I don't seem to be able to find it today. Old brain? Maybe, but T Pyx is waiting. Please, something simple and direct in navigating to use this fine program.
Thanks, Ed Wiley
