we are almost there: Emacs now asks about unsaved data, fine! 

And we use

(let ((default-major-mode 'org-mode))
(switch-to-new-untitled-buffer))

at the end of site-start.el.

However, if I start Emacs (the "untitled" buffer is in front, set to Org-mode, everything as it should be), then do a M-x c-mode (or python-mode; probably any major-mode will do), type something and then quit Emacs - Emacs does not ask about saving data any longer, so that problem persists.

Warm regards,
 Stefan
