Ordinarily I wouldn't have put this up, thinking it useless, but I've seen a lot of people here saying that they think nofollow links are valuable. If you are among these people then you might be able to make use of this: site:http://research.yale.edu inurl:wiki A lot of the results have PR 5. You can sign up to some of the the wikis and edit them with your link. Why am I posting this? I found it, didn't want to use it myself and remembered all those comments left by people who think nofollow is useful.
