The forums of old times still exist in some corners of the internet. They used to be big and there was one for pretty much every topic.
But most died over the years or got replaced by services like Facebook groups, Reddit or Discord.
Are you still using proper forums, which ones and why haven’t you made the switch to other forms of communication?
Easiest one that comes to mind is the archlinux.org forums. It pops up constantly in searches, even if youre not searching for an arch specific problem, so I used it even before daily driving arch. Now I have an account on there and have made a few posts seeking help. Most of the time though someone has already asked it, and someone else has already provided a solution.
