Forums Here I will layout different forums, and the ones I have used and ones I currently use. Forums I use Flarum ( https://flarum.org/ ) I still use at Tech Talk Forum My personal preference I used to use: Simple Machines ( https://www.simplemachines.org/ ) I think it was for an old domain and it was a tech forum.
