Looking for a NL plugin, I had almost resigned to using some bloatware package. You know the kind: needs another mysql user, has features as if NL writing is your sole business. I was only looking for a simple tool that allows a few hundered NLs to be send on a weekly basis.
To me, Wysija is the perfect solution: Simple and everything handled from within WP.
Installed Wysija from within WP3.3.1 nl_NL, installation worked perfect.
I did have an issue with posting a NL from any non-admin user, this was solved within a few hours by the Wysija team. Kudos to the Wysija team!
