How to contact Yahoo Inc directly and how to become a Yahoo knowledge partner?

Tony He.: How to contact Yahoo Inc directly and how to become a Yahoo knowledge partner?
Hi guys, I know it’s a dumb question but is there a way to contact Yahoo directly through phone or email.

Besides that, I would like to know what are the requisites for becoming an Yahoo Knowledge Partners. What should I do and I work in a medium size software portal company.

Please list some phone and email contact to yahoo.
Thank you in advance.

Tony.
