About the Full Name field

When you add or edit a user in the Webpanel, there is a "Full Name" field. In *nix lingo, this is called GECOS. This field is included in the password file on the machine, and so other users can "finger" the user for more information and get the GECOS in return. Historically that information would include the user's name, job title, office room number (early UNIX systems were primarily used in academic or research organizations) and other things of that nature.

For this reason, DreamHost does not allow users to enter domain names in this field, as this releases too much information about the user. It is preferred that users enter their full name, or any other name other than the domain name. You may not leave the field blank, but you could enter just a single space.
