NOTE: The Joomla contact form does one thing: collect the data in the form and email it to someone. It does not store the info in the database. You cannot modify the fields (either adding or eliminating them).
If you want a contact form with more flexibility, download one of the 3rd part Joomla form extensions, which can handle this for you.
