How do I disable the Chat function?
Navigate to the My Profile tab at the top of your page. A drop down menu will appear. Select Privacy Settings. A page will appear with all privacy settings for your profile.
Go to the bottom of the privacy settings screen and click on the box next to Disable Chat? Then click Save Changes.
You’ll notice that the Chat bar and Show/Hide arrow have disappeared from the bottom of your browser window. Chat is now disabled.
