The default Contact template comes with following fields: Your Name, Your Email, Web site and Your Message. Do I need to use Editor to add?
Download Contact form 7 plugin from WordPress.org http://wordpress.org/extend/plugins/contact-form-7/ This will solve your issue.
Thanks. I was hoping that I could do without external plugins since I only need to add one more field to the default template.
Adding extra field in theme's current contact form require lot of customization. Add "Contact form 7" plugin. It will help you for adding more fields in future too.
