Hello again,
thanks for getting back so soon!
1. OK
2. For users that are logged in to WordPress the choice to get notifications on replies or not is not visible. Default behavior is that notifications are not sent.
I ended up rewriting some of the logic in sending, so that no choice in database means yes instead of no (default). Problem solved for us, but I think default behavior in plugin should be that even logged in users get to choose (maybe something for the backlog?).
Love the simplicity of the plugin, thanks a lot!
