On the current default skin, a user visiting a Special Page only has one tab at the top, entitled "Special Pages". There's no Talk page or other obvious way to give feedback on the page. I've often had suggestions or complaints about various special pages, and had trouble finding where to post about them.
Could a tab be added to the top of all specialpages called "Feedback" or "Comment" or "Talk" or something? I don't know whether we'd be better off having a per-page "Talk", or whether there's an appropriate centralized location for Specialpage feedback.
