It's fixed now. We need to have a website revamp as well. Anyone willing to help? It's about the website content, what needs to be updated, what needs to be added/remove? Maybe open a new topic for it.
I'd suggest something more like IPS (Invision Community) as it has some great 1st party add-ons that could be useful.
Another would be XenForo, but the "good" add-ons for it are mainly 3rd party, and (even though that is what I'm using on my site) it's life expectancy has come into question by some (but I still renewed my license into latter 2025).
Discourse seems to be pretty popular for a lot of open source projects. No idea how or why those projects chose discourse but siril, telescopius, libre.space, orekit, arduino ... are a few that come to mind.
