I did not realize that PI was changing their forum structure - I just looked and yes, it is basically for bug reporting and development now.
I understand their perspective; there are a lot of forums where people can seek help with basic imaging methods, workflow examples, problem solving, best practices, troubleshooting, etc. - Astrobin, Cloudy Nights, Adam Block’s paid site, many others. But at the same time, I can think of instances where questions really did apply to the technical aspects of certain PI processes, were not bugs, and the PI forum seemed like an appropriate place to ask.
Oh well, life goes on and things evolve!
