Don't see Discourse ever mentioned, not to be confused with Discord. It's a popular forum platform, much like Slack has been. Not an expert, but it looks to me like the forum equivalent of BA given its feature-packed design.
Key takeaways at first glance:
- Open-source and free to use
- Can import existing phpBB content
- Your data is yours to keep
- Unbannable, unlike the Facebook group

My view is simply that a traditional phpBB forum has limited growth potential and will become increasingly less appealing to younger audiences over time. There's no doubt that activity overall has been dwindling, perhaps a migration could reverse that trend. I think anyone looking to build the best possible platform and community for trading already has the top tools available out there.
@mods Just a random idea, move the thread out of the Suggestions area if you don't think it belongs there.
