Using forum as a mailing list

Over time I have come to see that many people are not aware of all the points regarding how to use our forum in the supported parallel mailing list mode. I realise there is quite a lot to know about that is not entirely obvious. Therefore I am preparing a page about all the concepts and usage to be pinned on the site. I always emphasise that Discourse is not primarily a mailing list server and that the web interface is its primary function, but it does a pretty good job, and it’s certainly a valid mode for many users.
