docs.plone.org lists s&d as problematic

just stumbled upon this line on http://docs.plone.org/manage/troubleshooting/exceptions.html

> This happens when you have used Singing and Dancing news letter product. This add-on is problematic and does not uninstall cleanly.

does s&d still not uninstall cleanly? if yes, what has to be fixed?

if not, we should fix the text on docs.plone.org to something like

> This happens when you have used Singing and Dancing newsletter product. Earlier versions of this add-on are known to not uninstall cleanly.

Start by checking the troubleshooting page at docs.plone.org/manage/troubleshooting/exceptions.html and determine whether the Singing and Dancing newsletter product still fails to uninstall cleanly. If the behavior is fixed, update the referenced wording to distinguish earlier versions; otherwise, identify what needs fixing and document the confirmed behavior.
