This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file,
mt-config.cgi, to customize the behavior of the system.
This configuration directive specifies the maximum number of characters in the generated author basenames. These basenames are used to name directories in author archives. Regardless of this setting, generated author basenames will be at least 15 characters and at most 250 characters.
This directive was introduced in version 4.2.
