Several recommendations have come in over the years to set up an APR Discord server… which has now been done. I’m still in the process of configuring it and figuring it all out, but once it’s up and running it will serve as sort of a backup to the APR blog. It is something that seems to be available solely via invitation, so there will be some other little features it’ll have… such as, probably, even more restricted discussion forums specifically about Book 1 and Book 2 (“Book X” and “Book XX,” whatever) where I will describe them and post preview images such as representative diagrams, lists of vehicles to be illustrated, possibly early stabs at cover art, etc.
Subscribers to the APR Patreon and the Monthly Historical Documentation Program will all get invites when the time comes. I’m thinking of inviting the higher-level patrons/subscribers into the Book1 & 2 subforums. At the moment it’s pretty bare… there are channels for “Aircraft projects,” “spacecraft projects,” “aerospace news,” “aircraft – built” (as opposed to “projects), “general” (which is just for discussion of the APR Discord server itself) and “US Aerospace Projects,” which will go into further detail about the USxP issues I’ve released and plan to release.
If anyone has experience with such things, feel free to leave recommendations and suggestions in the comments.
