allows you to create a new user.There are some restrictions for the user name you enter for a new user:
• User names cannot include the following characters: #, /, >, \, and <.
• Because of known problems with the Apache and Sun ONE web servers, user logon names cannot contain multi-byte characters nor extended ASCII characters such as ä, ê, ì, õ, ǚ, æ, and so on.
 | Although the Participant Administration utility does not require that users have an email address, the following features in Windchill require that users have an email address: • Giving the site administrator privileges through the Site  > window• Giving the organization administrator privileges through the Organizations  > window• Enabling the user to create products, libraries, or projects through the Organizations > window• Adding the user as a member of a project through the Team window in the Project  context |
After a user is added to the table, you can manage the user.
