Fizzy keeps it simple here. This is where administrators can change the account name, manage people, and adjust the auto close settings for cards. Everyone can invite new people to the account here as well.

Open the Fizzy menu (J) and click the Account settings option located in the Settings section.

To change the account's name, click the current account name and after you're done typing, hit return (Mac) or enter (Windows) on your keyboard on your keyboard or click the "arrow" button to save your changes.
