I am using Org-mode in Emacs to handle all my technical documentation. I would like to use Emacs to prepare questions that I have for Stack Overflow. Is there an Emacs mode
This is less an answer than a test of my solution using the Edit with Emacs chrome plugin and the Emacs Edit Server configured to use markdown-mode for Stackoverflow (and other Stackexchange sites I use). All I had to do after installing the extension and MELPA packages was set
(setq edit-server-url-major-mode-alist
'(("mail.google.com" . org-mode)
("stackoverflow\\.com" . markdown-mode)
(".*\\.stackexchange\\.com" . markdown-mode)
("github\\.com" . markdown-mode)))
Note in the above setting, I'm using org-mode for gmail messages. Still need to do a little work here, but it is possible, with a little effort, to draft your gmail message using org-mode and then use org-mime to generate html from your org structured text. You could just use markdown and a markdown to html conversion.
