Mailing lists, for the most part, are only created for "official" department purposes (lists of students in a class created for TAs, etc). These are the steps to take to create one:

• Create a file of the people who should be on the list, one email address per line.
• Make the file world readable.
• Make all directories in the path to the file world executable.
• Email udb [at] cs [dot] utexas [dot] edu, giving the name of the alias you want, the name and path of the file, and the purpose of the alias.

The alias, if approved, will become effective within one or two business days.
