Actually, I don't think the newsletters are linked up any place other than the archive page (which has the drop down menu)
Each time a newsletter is sent out, the old one is saved as "newsletter/newsletterXXX.html" & the new one is uploaded to newsletter.html - so the links to the html pages are not link to from any place else on the site.
Doing a search in google on greenguysboard.com for "templates" brings up 5 pages of results - on the 3rd page:
http://www.google.com/search?q=site:...&start=20&sa=N
is a newsletter about the proper use of templates - so it does work
