I prefer to use a free open source platform instead of a paid platform. So I’m interested in using https://flarum.org
We use discourse ourselves (this site) and we implemented SSO with our portal. I don’t think it would be a huge deal to do the same for the web store (as a custom dev). If you’re insistent on using a different platform, it would be more time-consuming.
Can you open a ticket so we can add it to the queue for investigation, please?
