I would love to hear some recommendations for ways to build communities and discussion forums that are a bit more robust. Been seeing a minor resurgence of phpBB sites, as a reaction to the problems inherent in Discord and Reddit. When I research forum software, it seems like the space has more or less stagnated over the past 20 years, except for a couple paid offerings (like Discourse, which is $50/month). Some of the options I like in this space are newsgroups, majordomo mailing lists (with public archives), and phpBB. These pieces of software all had a long lifespan, and have some good qualities when it comes to archiving discussions and ease of use. Obviously, newsgroups are no longer a viable option. It does seem like we could do better these days, without outsourcing our communities to Reddit or Discord.
