Just a suggestion, it would be great if it were easier to do proper dash typography. I find TeX's -/--/--- convention for hyphen/en-dash/em-dash to be fairly intuitive.
Right now, if you do — in the text, it makes things much less readable and is confusing for newbies. The need for these glyphs is so common that wiki support seems worthwhile.
Cordially, Steven G. Johnson
