Every time your Mac connects to a WiFi network it will remember this connection. This is very useful when you connect for a second time as the time it takes to determine the wifi connection is reduced. However, if you connect to a lot of Wifi networks this list can grow. This is OK most of the time, however if you want to order the wifi list within system preferences to take advantage of preferential network connections, ordering this list can be time consuming. This video shows you how to delete these networks and keep the list ordered. It is only a simple trick, but very useful.
