A UserTab is a personalized tab for a specific user. This user can potentially change the pagelets that appear on the tab, the name of the tab, and the order of the tab. All these changes can be allowed or denied on the TabDefinitions Class. The UserTab is used in place of the TabDefinition whenever a user has personalized a tab.
A UserTab object is instantiated from the First, ItemByName, InsertItem, or Next UserTab Collection methods.
See UserTab Collection.
