Two Guides about Writing Email

Even tho it's a bit long, this is a very good guide for anyone new to email or to mailing lists, A Beginner's Guide to Effective Email. It's public domain so you can take what you like from it, adapt it however you wish (see the "copyright" link at the bottom of the first page).

And this one is good too, Mailing and Posting Etiquette, it's shorter but it covers the important points. There's no copyright info here so it would be better to only quote excerpts and give a link back to the site for the full document. Or take the ideas presented and rephrase them in your own words. There's also some links at the end to other sites.
