I was under the impression that you would have to create an account and only alums could create and account to post to edu blogs. This is new and fruitful information, thanks for sharing.
I picked 25 links at random from the list and checked them. One of them might be usable... www.uoregon.edu/~mspp/guestbook/guestbook.html The remaining 24 had at least one of the following problems: -Nofollowed -Comments not allowed -Comments require owner approval / and they're not approving any -Dead Link ...your mileage may vary. ^F^
great list - btw - who cares if they are NF - that's more of a rumor going around - according to Matt Cutts
Can I ask why are .edu domains so great for backlinks? Do they provide more Google PR juice or better quality backlinks somehow?
