Settings can be made from both the administration screen and the application.

On the administration page

This can be done from the menu Users.
Once there, you will see a list of staff accounts. Click on Edit for your account to go to the edit screen.
If you do not see your account listed, please use the search function in the upper right corner and enter your email address to search for your account.

For Apps

Settings can be made on My Page, which appears immediately after logging in.
