I found this in the help docs:

Changing menu labels

In order to change a menu label, you will need to have access to the resource files that are located in the sub folder of the templates folder in the Gemini web application. If you create or amend an entry that exactly matches the menu name then the menu and any attributes that are identically named will reflect the value in the resource file. For example if you had an entry in “resource.xml” in a template folder that was: Stories then the Items menu would be renamed “Initiatives”, as in the screen shot above.

I created a new template based on Agile and wanted to change the references to Story and Stories. I change the resource.xml file in my new template folder but the labels in the user interface did not change. Do I have to change something else to make this work?
