Send an email to listserv@listserv.indiana.edu with a blank subject line, and a note that says "sub COPYEDITING-L yourname" (without the quotations and write out your name where it says "yourname"). It is fairly high-traffic, but a great list.

If there's a spot that will have this discussion, that'll be the place.

How can we use typography to further emphasise the emotional qualities of the written word?

Why would we want to? It seems to me that if you want to employ emotional markup, then you need something other than punctuation as we have inherited it, because punctuation is doing a different and important job: it is marking the structure of text, and thereby helping us to avoid ambiguity of meaning and to communicate thoughts effectively.

Of course, people use the bits and pieces of typographic punctuation to make emoticons such as ;) but that's using punctuation signs for something other than punctuation. That's fine, but you shouldn't confuse the two things: punctuation, which indicates structure (very precisely), and emoticons, which indicate emotions (very crudely).

Do you know ‘Fisches Nachtgesang’ [The Night Song of the Fish] by Christian Morgenstern? It is said to be ‘the deepest poem in German language’ …

And, of course, check out John Harris: Punctuation Personified, Or Pointing Made Easy By Mr. Stops, a charming old children's book. There used to be an online version, but that seems to have disappeared. Still, you can have a look at it via the wayback machine – unfortunately the text there got black on black; in order to read you have to ‘select all’.
