You can use Ajax to request their user page, and in the json it should specify all of the groups they're in.
ah sorry forgot to reply here,
meantime I found out, that its not a problem in custom JS to use app.user.groupTitle 🙂
it works fine so good
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.
