It is possible to change the name of my Sub site Navigation? At the moment I have two links, One is called Issue Log which takes me to my homepage and the another also called Issue Log which takes me to a custom list. I would like to rename the Homepage Link to be Issue Management
You can alter the navigation items from the site settings page:
You can access this section from the Settings cog too:
Use the controls to add, remove and edit links. You may need to create a new link called "Issue Management" and have it point to your list.
