I upvoted solely for the use of an en dash ( – ) in the title, instead of a hyphen ( - ).

Probably comes down to personal aesthetics, but I find it looks so much nicer!

For users on Windows, I recommend setting up an AutoHotKey script to convert the string "==-" to "–", and "===-" to "—".

Easy to type, very intuitive (typing more characters gives a longer-width dash), and gives your carefully crafted email missives a lingering, hard-to-describe dash of style!
