I need to transfer my contact details from one yahoo email to another email address. How do I do it?

I have a yahoo email address. How do I transfer all my addresses and contact details to another yahoo email address?|||If you go into the addresses, on the right top corner there are the Import/Export to click on. When you go into that screen, you have the option to export to Outlook, etc. I would choose the csv export as it is read by most programs. On the other hand itf you're using Outlook, you would choose that. The rest is quite straightforward.|||i dont think you can but you make another address book...usually its the IP that will allow what you are describing in their acct..
