plus mark

In the left top window, identified as "News Server" you will see the name of all the news groups your server's news feed carries. At the very left of that window are folder icons, if there are subgroups within that folder. If there is a plus mark to the left of the icon, it means there are groups within that folder that you might want to look at. Click on the plus mark to list the subgroups, click on the minus sign to close that folder.
