About [[MediaWiki:Moodbar-what-content/en]]

You can phrase Moodbar-what-link (“feature page”) any way you like to make the sentence work. moodbar-what-link will be the linked part of the message, but which parts you put in where is irrelevant for the logic. I have also made a request at mwr:92783 to change the message to "[$1 link text]".

Yeah, that's what I ended up doing: making "feature page" more like "featurepage" which is legal in esperanto. Thanks!
