Employees & Interns of NodeBB
@Kichae yeah let's say a topic is forked in NodeBB. The baseline expectation is that federation doesn't break, but the ideal is that the fork is also federated so Lemmy (for example) would also fork the topic on their end, so it looks the same on either end.
Something we'd want to work on with ForumWG (specifically @[email protected])
@nhl.pl What documentation we do have is actually already on our documentation portal: https://docs.nodebb.org/activitypub/
Let me know if that helps, or if you need me to flesh out any sections.
@Kichae @[email protected] That's an issue with all software federating via ActivityPub. If there isn't an existing follow relationship then the content isn't pushed to that user.
That's greatly simplifying it, of course. There's quite a bit more that actually goes into how it works.
In the case of the referenced topic, NodeBB automatically boosts replies that it receives from the category actor. When replies are made by NodeBB users, they are also addressed to everybody who has participated in the topic.
So given that, lemmy.ca should have received everything, at least since you started posting in it. In reality, there might be a connection issue between NodeBB and Lemmy, and that's what I'd want to verify first.
@[email protected] whether replies from here appear on lemmy.ca depends on whether a user from lemmy.ca follows a user here. Perhaps that isn't the case? (Hopefully you see this reply now 
)
Still need to debug Lemmy federation. Might be a regression.
