System Labels are static comments located throughout the system. For example, “Your recent client searches accessed” shows up in the right side of the search screen, and “You are banned” appears when users try to log in with an incorrect password 3 times or more.
System Labels can be managed by going to Setup > Settings > Advanced Options (right sidebar) > System Labels. This link will take you to the System Labels main screen.
You can edit a particular System Label by mousing over the label and selecting the edit link that appears to the left of the margin.
This will take you to the Modify System Label screen where you can modify the System Label by altering the text in the Message box.
Remember to select Save Changes at the bottom of the screen to apply your changes to the system.
