I’m curious to understand how your **Expose Email In** plugin actually works in Discourse. Thanks! We’ve set it up, but I see no specific documentation on how it works.

It adds an envelope button at the top of category pages which have a “custom incoming email address” configured:

Thanks, got it. I was looking for two other features…

- Adding that button to the landing page ala [https://discourse.mozilla.org/](https://discourse.mozilla.org/)  
This would mean the button would send the email to a specific category from the landing page afaik.

- Adding some sort of Subscribe button, or way to explain how Discourse categories can mirror a mailing list.
