Forget ghost!
NodeBB is not only FLOSS, it's also a great federated forum software!
Just look up julian@community.nodebb.org
This is a profile on NodeBB but you can watch so many posts and if you select
"Open original page"
it will take you to the forum and make Mastodon and the fedi look nice!
I feel like NodeBB could be the next Mastodon!
It's amazing!
