A forum isn't required to build community around your work. The core needs are simple: let your audience hear from you and talk to each other. Local meetups, Luma office hours, or showing up in existing Discord servers work just as well.

You don't need a forum to make a community. I often talk about community as one of the 4 C's of intellectual property businesses. And sometimes you get like, hey, should I make a Slack? Should I make a Circle? Should I make a forum, use Discourse or something? And my answer is that the point of community is to provide people who are aligned with you with a way to hear from you and a way to communicate with each other. And those are really the North Stars. So what can those look like? One thing it can look like, particularly if you've got sort of more of a local thing, is to make it into a meetup. Or even if you're going to be more remote, this is where Luma becomes really interesting way for people to come together and have like, you know, like office hours or meetup or what have you. It's super, super powerful. You can have something which is sort of running inside another group, like the NoCodeProCode founder, Yacine, has his habit of showing up in Discords of these products that he is an expert in and is able to provide a lot of value. In both these cases, you have community and neither of them do require your own forum.
