I’m hopeful for assigning activitypub actors by tag as opposed to category. I think this would also work through chat-integration plugin support, plus that would allow further content filtering.
Another interesting idea would be to put every activitypub post into a queue for admin and mod approval before it goes live. This would be great if it could allow a group to confirm whether the topic was ready for crossposting. Same could apply to replies, rather than auto-posting them from the fediverse back into the forum.
Thanks either way for working on this awesome plugin.
