How to change yahoo registration information
 

Hi,

I am one of the frustrated yahoo mail users in this forum who have lost their yahoo id because it hacked or forgot password.
I lost access to my yahoo id today and can't remember the registration information.It just makes me sick thinking that someone else reading my personal emails and information.

Anyone knows how to change the information I provided during the yahoo registration.So that I can be safe for the existing yahoo accounts I have. Kindly help me.

Thanks
