how can i see someone contact list
Yes, if you have Yahoo messenger and someone else has windows live, you can add them on your instant messenger contact list and you will be able to talk to them.
i just found this https://help.yahoo.com/kb/messenger/SLN1278.html?impressions=true
Preferences, ignore list.
how do you change the background for yahoo
ask them!
It is on the bar of the top:messenger-preference-ignor list
No; occasionally when using different versions of windows live messenger; the contact might have you added and it just doesn't show. A long with this if someone blocked you and kept you added; it would still show them as having you on their list.
Click Messenger at the top and you'll see preferences on the list that drops.
yes u can still see them in your list but the type /font has changed from the other contacts
Download the newest version.
go to the bottom of your yahoo list and hit add a contact
It means you're not on their buddy/friends/contact list.
