If, for some reason, the details of a user must be modified, like when his or her email address has changed, you can make changes to that user’s data.

To modify a user, please follow these steps:

1. Log in as Administrator (or a user who has the ‘Manage System Settings’ permission). If you are already logged in, skip this step.
2. From User menu | Company Settings, select Users. This will open the Users screen.
3. Click the name (hyperlink) of the user you wish to modify. This will open the user details section on the right side of the screen.
4. Make changes as required—all changes are saved automatically.
5. Click "X" in the right top corner to close the details section.

See this page for the specific section of each user detail/info
