The (small) community of Portuguese Wikibooks has agreed (see URL above) about the installation of the extension ReaderFeedback on that wikiproject.
Could someone please install it for us, and make the needed configuration so that it appears on "main", "help" and "project" namespaces?
$wgFeedbackNamespaces = array( NS_MAIN, NS_HELP, NS_PROJECT );
The variables $wgFeedbackTags and $wgGroupPermissions can be left with it's default values.
Thanks in advance.
