We are using iContact as our email distribution provider and they have a feature that keeps all of our old newsletters for us. You can check them out online at http://community.icontact.com/p/cinnug. A great thing about this feature is that it also offers a RSS feed! Look for the RSS icon in the top right corner below the page header. So, if you don't want to get email you can still keep track of the same information either via the CINNUG Blog or the RSS feed for the newsletters.
