I recently discovered NodeBB can federate and started hunting for interesting instances. I’m into tech, literature, and indie games but haven’t found an instance that fits. Could anyone recommend NodeBB instances with active communities focused on those topics? Thanks!

There are comparatively few instances that federate, since we are new to the activitypub game.

I made the decision that if you upgrade to v4, AP is turned off. Install a new instance of NodeBB, and ActivityPub is enabled out of the box.

Side effect of that would be all instances running prior to v4 won't be federating, but at least there will be no surprises!

Here's a list, but it's not listed by topic or genre.

I checked some of the forums in the link (https://nodebb.fediverse.observer/list) you posted, but it's hard to tell what most of those NodeBB instances are actually for: many lack descriptions and the forum names don't say much. I would have to read a few posts in each forum to figure out what each one is for. I found a literature forum but it only has three posts, I don't want to make an account just to shout into the void, so I'm trying to post to it from Lemmy.

I tried posting to the literature community I found via Lemmy but the post never showed up on the NodeBB instance. I used Lemmy's search with the target community URL (https://community.darkscribes.com/category/2/general-discussion), it found the community, and I created a post from Lemmy (https://lemmy.dbzer0.com/post/54997372). I can see the post on Lemmy but not on the target NodeBB instance. Any idea why that might be or how to get Lemmy posts to appear on federated NodeBB forums?

Oh, I'm sorry to hear that... unfortunately debugging server-to-server interactions is kind of tough. It should work though, so I don't know why it didn't... yet. It could be their version of NodeBB isn't up to date enough.

cwsmith@community.darkscribes.com cwsmith@community.nodebb.org are you able to weigh in and let me know the NodeBB version? Could also be a privileges issue with the fediverse pseudo-user.
