Yes, I think it was enabled by default when I installed NodeBB:
A Markdown parser for NodeBB
Installed 8.9.2 | Latest 8.9.2
in the confirmation email there is an error.
the url is to confirm erroneous .. it is only the localhaost/xxx
but it would be the url from the config.josn ..
So he sends me to confirm link : http://localhost:4567/confirm/fa2044ba-37e0-4698-b758-843ad609adbf
but it would look like this : http://humanistischefriedenspartei.de:4567/confirm/fa2044ba-37e0-4698-b758-843ad609adbf
Actually the email does use the url from config.json. Check it out here
