Please here an idea to improve the Contact Form (sorry, I know what you have written). In the options of the plugin, please create an opportunity, the "subject" field to disable this as in other fields is possible. The "Subject" field does not make sense, if the drop down menu is activated and this subject can be selected. That's double/twice content and does not look good. (Hi, That's not me, it's Googel-Translation ;-).
