This video is based on an older version of Wordpress (3.1 version). In February 2014, we upgraded to version 3.8. While the interface looks different, the instructional process is very similar. When going to activate your AddThis plugin, you will notice the plugin display has changed slightly. The activate button can be found directly below the AddThis icon. Once activated, select Details in order to find the settings option shown in this video. From there, follow directions based on the video.
