Gmail Chat is a free service integrated into your Gmail account. Unlike other chat applications, you don’t need to download or install any software to access the service. When you activate a chat session in Gmail, the chat window opens in the Gmail account window. However, this is inconvenient if you have more than one window open, because to continue chatting, you must go back to the Gmail account window. Fortunately, Gmail allows you to pop-up the chat session so it is in a window completely separate from the Gmail account window. Writer Bio
