On Lee's test site (http://www.piclab.com/wikitest/wiki.phtml), I have patched the stub detector so that /when the stub detector is active/, it will also show links to redirects with a yellowish background.
Should I use that on the live software 1. not at all 2. only when the stub detector is activated 3. for all logged-in users as an user option, off by default 4. for everybody
The most simple implementation is #2, and it doesn't require an additional database query. That's what I will do if I don't here good arguments against it ;-)
