On http://nginx.org/en/community.html there's a link to https://community.nginx.org/joinslack to join a Slack workspace for nginx. However, the signup process seems to be broken. After you fill out your information you receive an invitation link email, but clicking the invitation link results in

This link is no longer active
To join this workspace, you’ll need to ask the person who originally invited you for a new link

Is the Slack workspace still active? Should all questions just go to forum.nginx.org instead?

Thanks.
