I just tested this Extension. I like the idea and would love a Newsletter that I can manage completely from within the wiki (Thanks for development so far!).
When publishing a newsletter, subscribers receive an email saying something along the lines of "a new issue has been published, find it [here]; [and a quick summary typed when publishing]". Is it possible to include the actual newsletter in the email subscribers get? Or alternatively: modify the content of the email that is sent out?
I don't want to count on people opening a browser window to see the contents of my newsletter, but rather serve it to them in their email inbox.
