How do you block someone on facebook chat?

[Erin Mcdermott]

To block someone on facebook chat click "friend lists" a menu appears in the box that says "type a list name" put in whatever you want to call the group. Once its named it will appear in the menu with people to chat with. Click Edit next to the group you just named and you can add people you don't want to talk to or see. You'll notice that there is a green little slide bar. If you move it over so its gray you appear offline to whoever is in that group. To let them view you just move it back to green. They may not appear on chat if they unfriended you, they blocked you, or they changed their chat status to "offline". Hope this helps.
