I got an email reply from Josh yesterday.

The content of the message was mixed, some of it being directly to me/personal, and other parts related to LT/the forum, so I'm going to detail what he said regarding the LT stuff.
First, and what makes me feel the most relieved: The forums aren't going away!

Josh has it set up so that we (I? Surely I wasn't the only one) don't have to worry about it anymore, and it's paid for. From what I understand, Josh managed to get the job he mentioned he was angling for earlier this year. He said that it keeps him very busy, but he seems happy with it.
Regarding the source code: In his words, "I've already uploaded everything to a private GitHub repo and have been working on it when I have the time, trying to fix up the build process, dependencies, etc. to make sure people can actually use it (especially the engine). Sadly, it's taking a long time simply due to having a full-time job and working on relocation at the same time."
I did tell him in my reply that he doesn't need to bring presents every time he posts, and that we'd prefer hearing from him without presents over not hearing from him at all.
