Sara, Paul did it exactly right. The only change I would make in his example citation (the one that used your name) would be to remove the period before the URL. A period follows the date of upload given earlier in the citation, but there is no period between the date you accessed the site and the URL for the site.
The rules of copyright are the same for any published work; that is, there is a certain amount of latitude given for quotations for an academic work. They can be longer than would be allowable for any other purpose--but only if each quote or paraphrase is properly attributed in the body of the paper by author's name and title (e.g. In "For the Greater Good," Wendy Richards writes--followed by a comma if it is a short quote or a colon if it is a long one). Don't forget to cite your paraphrases, too. Unfortunately, you can't add that wonderful paraphrase-or-quote-ending parentheses with the page number in it since html articles aren't broken into "pages" the way a pdf document would be.
