Dear all,

I'm writing to see if there's anyway to use org-like outline in ALL kinds of files, like my emacs configuration file, whose suffix is .el. Could I tell Emacs

;;; headline 1
;; headline 2

And it begin to have the ability to display my el file just as Org does?

Besides, is there any active mailing list of common Emacs questions?

Any suggestion is welcomed, thanks!
