luceos That's sad. Not near active at all. ? Discourse powered forums however, many examples.
Hoped for a few, as it in some cases, hints as to how effective the UI and notification/user system etc is in retaining users and promoting activity. I'm running a test with both and find a lot more Flarum signups pass right through, sign up and then that's it. Whereas Discourse seems more effective at user engagement.
No matter how good Flarum looks, its success will probably be determined by how successful forum owners can be in converting traffic to active users.
