What is a username?
A username is the name you use to login to Disqus. A username must be unique, and cannot be in use by more than one commenter at a time. A username cannot contain any spaces or special characters.Usernames are used mostly for two purposes: logging into Disqus, and moderation (for site owners).
What is a full name?
A full name is the name carried across the Disqus network on your profile and is the name displayed with your comments. Your full name does not have to be unique and can contain spaces.
Full names are optional, though highly recommended. For added security, we recommend choosing a full name different from your username.
Where can I change this?
You can update your full name under the Profile tab at your account settings, and your username in the Account tab.
