Ember.JS digest info@discourse.org
That is the notification_email setting which is described
The return email address used when sending system emails such as notifying users of lost passwords, new accounts etc
Discourse.org does in fact host this forum on our servers, so the address is reasonably correct.
And if you email info@discourse you get an automated “this isn’t for replies, try these URLs” response. If there is a better @emberjs.com non-responding email address to use, we can change it to that. Otherwise this one may suffice…
