• Answer:

  Yahoo will never reveal the real mail address of a user, that is considered to be private information. But if your friend is active on YA, you may be able to get in touch with him by using the internal mail system. Here's what to do: click on his avatar to enter his YA profile, if he allows mail contact, you can use the link provided to send him a short message. Note: this only works if you allow mail contact too. I checked your profile and found that you don't allow this yet, if you want to change those settings, click on <edit my preferences> and look for the mail contact allow settings. And don't forget to save your changes!
