The Servers window lists the news servers that you're using. Hit Add to create a new server and Remove to remove one.When a check mark (tick) appears on the left of the list, this indicates that the server is Enabled. A server that is not enabled will not be used to download headers or articles from. You can temporarily disable a server if, for example, you have reached your download limit from a particular server, but want to continue using others.
Double click a server in the list to display the Server Settings window.
