+Hello,
+
+First of all, notmuch is a wonderful idea, both the cmdline tool and
+the emacs interface! Thanks a lot for writing it, I was really excited
+when I read the announcement today.
+
+Have you considered sending an announcement to the org-mode mailing list?
+http://org-mode.org
+
+Various ways of searching/referencing emails from emacs were discussed
+there several times and none of them were as elegant as notmuch (not
+even close). Maybe notmuch would attract some of the developers
+there..

+
+ Ah, here's where I planned a nice welcome. So welcome (again), Jan! :-)
+
+ I've been having a lot of fun with notmuch already, (though there have
+ been some days of pain before it was functional enough and my
+ email-reply latency went way up). But regardless---I got through that,
+ and I'm able to work more efficiently with notmuch now than I could with
+ sup before. So I'm happy.
+
+ And I'm delighted when other people find this interesting as well.

+
+ Thanks for the idea. I think I may have looked into org-mode years ago,
+ (when I was investigating planner-mode and various emacs "personal wiki"
+ systems for keeping random notes and what-not).

+
+ Yeah. I'll drop them a mail. Having a real emacs wizard on board would
+ be nice. (I'm afraid the elisp I've written so far for this project is
+ fairly grim.)
