The English forum used to reside at https://trisquel.info/en/forum/users but has since moved to https://trisquel.info/en/forum/trisquel-users
The old location gives a Page not found, perhaps it should be redirected instead.
(this did happen some time ago but perhaps this would still be useful)
That's the URL I used to point my browser to. There might be other external links.
In what case do you get linked to https://trisquel.info/en/forum/users?
