I do not think so, but I have never tried it
you can either go to the main yahoo page and click sign out or you can go to the top of the computer screen next to where your login name is and click sign out. hope this helps :~}
The same way adults do you go to sign up now!
You must sign out of yahoo and then sign back in using their e-mail address
You have to first have a yahoo mail account and then you download yahoo messenger you can get it at: http://messenger.yahoo.com/ Then, you sign in your yahoo mail username for your messenger username and the same way for you password.
Yahoo has an email service where people can have their own email address for free. People can sign up at yahoomail.com.
Yahoo now as the option to save your password on your computer for 2 weeks.
One can sign up for the BT Yahoo Mail on the official page of BT Yahoo Mail on the right hand side. One can also find a tutorial on how to sign up at BT Customer help section of the same website.
You go to yahoo homepage then on your right handside their will be a sign that says " sign in " underneath it will say sign up click on it and follow the instructions

Yahoo has more things but I prefer Google !My brother prefers Yahoo because the email sign is already there and Google is too simple !Yahoo has pictures and events !
UNFORTUNATLY, i am pretty sure you cant. Yahoo only limites you to the people that you email, or have in your email-adress book. It also only limits you to only people that uses Yahoo as well. Also, Unlike GMAIL, if you have an AIM account, It dosent allow you to sign on as that. With GMAIL, you can sign on with your AIM, YAHOO, OR GMAIL instant messaging account.
