i found out how to edit the nl - thats fine for beginners, but not really easy to work out ...
But when i like to save the freshly edited newsletter there came a message-popup telling "Error while saving ( ok)" (deutsch/german:
Fehler beim Speichern: ( ok))
huh, what does that mean?
i ask because if i leave the nl-editoring-mode and ignore all the warnings, do come back and i can find that all changes did save although ...! ;-)
another thing i didn't found out,
- how to give an newsletter unsubscribe link to the subscribers?
- and how to add it as a link into the newsletter?
