Have you made any progress with this? It sounds very interesting.
As an enthusiastic Discourse user, the one thing I’d like would be to be able to convert an existing email thread into a Discourse topic - with the authors and times preserved and all the gumpff removed.
The reason for this is the human tendency to kick off a group conversation by email, and then after 10-20 reply-alls someone realises and says “shouldn’t this be on the Forum”? By then it is too late…
Doing this manually is soul destroying. But if this API could be harnessed to do that somehow - wonderful!!!
