Description:While other email providers have separate chat applications available (Windows Live Mail, aka Hotmail has Windows Live Messenger, Yahoo! Mail has Yahoo! Chat, for example), Gmail is unique in that it integrates its chat messenger into the email client. If your Gmail contacts choose to be visible and are online when you need to send them a message, Gmail Chat allows for an instant response to your question or comment. Chats can also be stored and archived and are searchable, just like email.(2:58)
