The Pins Team (currently just me) started a new forum for discussing our open-source projects on GitHub and GitLab, our official newsletter on Medium, among other random stuff. It's still in very early stages and our forum is proudly hosted on FreeFlarum. However, thanks to the awesome extensions the Flarum community provides (and available as per FreeFlarum's standards) it's off to a great start feature-wise.
Still in progress in matters of Authy integration for 2FA, site design/logo/favicon, rules, and other stuff.

P.S.: Our domain is currently using a free domain and will move to a better domain in the future. We're fine with the FreeFlarum banner ad, as this was better than having privacy-intrusive ads in our forum.
