I was having the same questions and I am frustrated that it does not have the option to send out the latest newsletter.
Is there a way to have the newsletter on a webpage so that for those not signed up for the newsletter email to be able to read it online?
Why would you be frustrated, you are talking about a newsletter not a latest emailupdate. If you looked at the extensions you would see the archive-extension showing all old newsletters for reading back the old news.
