@Jim-Bridger moderators don't have the ability to adjust group membership, unless they also happen to be owners of said group (which if you're creating a custom group, is doable)
Then they can add and remove users from the group details page.
The list only currently shows plugins known to work on the version you're using. After I build automated testing for plugins I'll add a secondary tab which will let you install plugins that haven't been updated (but probably works anyways)
So, you'll need to
npm i nodebb-plugin-emailer-local manually, the startup log will give you the command to undo it if it doesn't work.
As of version 1.0.0 NodeBB has by default enabled sendmail transport plugin. So it's enough to make available "sendmail" command in your system.
For example on Debian Jessie with postfix installed you can do so with symlink:
ln -s /usr/sbin/sendmail /usr/local/bin/sendmail
and test it like:
echo "Test mail" | sendmail -i -f [email protected] [email protected]
Note: I know it's an old thread, by I want to make it clear to those who comes here from google, like me.
