Often a question is asked that I'm reading and although I don't know the answer, I know who does. Is it possible I can ping a user and have them receive an email notification from a comment? e.g. a comment like "@bob, can you take this one?" which causes Q2A to generate an email notification to bob?
Is there a plugin that allows this, or is it possible in core and I missed it?
Presumably the permisison for this would need to be admin-controlled. In my environment, I'd let any registered user do this, but I can imagine others that would only let experts and above do it.
