You're the only user here who's mentioned ActivityPub, so I think we're on the same wavelength. Has the flurry of development and growth piqued your interest at all? I'm researching forum projects and wondering if you've done the same.
so after how much time does xenforo actually add the last edited message in edited posts? i spent like 30 minutes looking into how a user was able to bypass the last edit message label on one of his posts.
