Those interested should educate themselves in exactly how the plugin works: ActivityPub Plugin - Plugin - Discourse Meta as it will help your suggestions to Techlore be the most helpful!
My .02 is be sure of which categories or types of posts you actually want relayed with the fediverse. People here seem to enjoying anonymizing their postings and such as time goes on… you also want to make sure what you are posting to the fediverse makes sense as opposed to spammy.
Example, relaying each top post from an announcement or news category to the fediverse.
You’ll need to consult the meta discourse linked above, or even ask questions there, to confirm it will actually work in the manner you are imagining. Remember, content posted to the fediverse will never go away. 
Don’t surprised if some members of the forum find relaying messages off-putting & invasive.
