I would suggest contacting yahoo and asking them admin@yahoo.com

Page Rank is related to Google only. We can not check PR in other search engines. Although you can check only back links in other search engines.

You can check your backlinks at Yahoo! by searching for "site:www.example.com" if example.com is your canonical domain name. But PR is a Google patented measurement of link popularity. The other engines have similar things... but they don't expose them in their toolbars.

Wow... Only Google has pagerank mate.
