By the way, I'd like to say two things concerning this thread: 1.) In case you may find new relevant information before me (which is possible), please post it here and I'll add it in to the title page.
2.) How do you like the new "streamlined" design of the title page? Any requests or ideas for improvement?
I just looked back at the first post in the thread for the first time since the thread was created, and I have a question (or I guess more of a comment).
On May 20, 2020, JR posted a picture of a screen of music notation with the caption, "In case you are wondering what I’m working on in the studio." Why are you interpreting that to mean that he is "collecting ideas" in connection with DT15?
Similarly, on April 14, 2020, JP posted a photo of one of his guitars with the caption (in pertinent part), "spending many hours practicing and creating a lot of music on this beauty!" Again, you've got this under the "collecting ideas" heading.
Seems to me that neither of these posts have anything to do with DT15.
