Tired of seeing that pesky chat window on the left side of Gmail? There are plenty of reasons to get rid of it. Perhaps you have Google Talk installed, perhaps you don’t like instant messaging, or maybe you just use a different service. Getting rid of the chat box is easy, just follow these simple steps.
Log in to Gmail as you normally would, and then click the Gear (settings) button at the top-right of the window and select Settings.
Click the Chat tab and select the Chat Off bullet option.
Scroll down to the bottom and Save Changes.
Done! Now Gmail will no longer pester you with annoying chat requests and you’ll have that much more room on your sidebar.
If you are working on a smaller screen, this is quite a luxury. The only downside is that you won’t be able to make Voice Calls via Google Voice anymore, but you can still install the Google Voice extension and send text messages.
