[O] org-mime-org-buffer-htmlize sending hangs ...
I've used org-mode-org-mime-htmlize in the past to send email from org, via Gnus. However, recently I've discovered that after I edit the To: field and enter C-c C-c, I get Sending via mail... in the mini-buffer, and then emacs just sits there, apparently hung. Typing C-g enough times brings it back, but the mail never gets sent. I have started running Gnus in a different emacs concurrently on the same machine (On OS X, I run org-mode in emacs-mac-port, and run Gnus in Aquamacs), using the same .gnus.el, but I would not expect that to cause any problems. Any suggestions as to what may be going on here, or how to trouble shoot it? I really like sending nicely formatted emails from org.

This might be a bit too complicated to learn on, but I would encourage you (and everybody else too) to learn both. My favorite quote in this respect was somebody's post on this list, who was caught completely by surprise at having learnt enough lisp to do useful things, and he wasn't even trying :-) I wish I had kept a reference to that mail: if anybody (perhaps the author) recognizes it and can find a reference, please let me know! I'll also mention that I'm pretty sure that neither John Hendy nor Tom Dye knew much (anything?) about emacs lisp before org-mode entangled them[fn:1] - and look at them now! Footnotes: [fn:1] That's a little known feature of org-mode: in addition to exporting documents and tangling programs, it also entangles people. Instead of a unicorn, the logo should be an octopus :-) Nick
