Great work @baris! Will update and report my findings.
Using NodeBB as mailgroup
I'm starting using NodeBB. It works great till so far.
The most important functionality of my site is email notification. The only way I know to do this is asking everyone to watch a thread. But this is not straight forward.
What I want is some utilities that can send emails to all the users in a group. Is it possible with current version?
P.S. I think notification to all users when new post in a certain category suffices.
