You can rename your showcases at any time, as many times as you like. You DO need to publish them each time, to ensure all your users see the same title. 

Here's how you do it! 

  1. On the Home tab, click ‘Edit’ under the showcase you’d like to rename.

  2. Next to the title of your showcase, click the ‘Edit title’ button, which looks like a pencil inside a box. See here: 

  3. Rename your showcase and click ‘Save’. 

    You will need to publish this change in order for it to take effect.

If you're in a super hurry, there's also the option to 'Rename' from the "More" dropdown on the home tab. It's last on the list.
