AAron sent me a detail reply that makes good sense so I decided to share it:
The IAA BOD wanted a managed solution rather than one I (or Chris Brady, or a single person in the organization) was responsible for and ran on my own hosting. And I agree that this is by-far the best decision even though it costs a little more.
But also that means that I have little control over features of the forum.
This is exactly like having me install Microsoft Office on your computer and then complaining to me about not liking a feature in Excel.
However, like mentioned in the forum topic about this, I asked the creators and maintainers about adding a feature and provided an update recently: Problems with the new forum
And feel free to peruse the actual code changes for this. https://github.com/discourse/discourse/pull/4366
I checked and it looks like the “PRINT” command is actively being worked—good news.
I fiddled around and tried using the print command on my Chrome and by moving down from the top, I can get a lot more of the thread printed, and then stepping down further, I can get the full thread printed in two or three prints on the ones I tried.
I actually print to a .pdf file so I can combine the various results and get a single pdf file with little overlap and no blank pages. This will serve me for now.
