yes, PSRTutorial is now gone. It was a treasured resource for 20 years, a lot of us are really sad to see it go. Still trying to see which forum overover (Chris) and pjd end up using. Good to see you, Drake!
Basically exactly what Maakr said: as per Roger, server upgrade won't run the old software, they refused to roll back the update, so end of story. Yes they were about to announce the end either this year or possibly even another year, but didn't really get a chance to announce anything thanks to their hosting service breaking their forum (it seems kind of crazy to me, that the server hosting folks don't realize that if they make a forum unusable, they themselves now lose a long term customer.
