Like:
Hey, can you check out the redirects if they are still usefull [[Special:ListRedirects|over here]]?
Please elaborate on what you are thinking here, because it is impossible to look into your brain. The current fiberglass internet connectivity does not yet provide for that, i already filed a complaint about it, but the companies employee did look rather sheepish at my complaint.
(that, my friend, is a joke)
BTW, along the road, over the hedge:
Categorial pages already check if pages are redirects and displays them in italic once they are found to be redirects.
