With Mor, you have the option to change your profile title that'll appear at the beginning of your Mor. If you prefer to leave your profile title blank, your username will be used as the default.
🔔 Note: Changing your profile title is not changing your Mor link username/URL.
Steps:
In your Mordashboard, head to the sites.
Choose the site you want to rename it.
Click on Modify.
Below your profile image, there'll be a Profile headline field.
Enter your new Profile Title. Your update will be automatically live on your Mor.
