WP Contact Form III is a simple contactform based on Ryan Duff’s <a href="https://wordpress.org/extend/plugins/wp-contact-form/" rel="ugc">WP Contact Form</a> and <a href="http://www.douglaskarr.com" rel="nofollow ugc">Doug Karr’s</a> challenge (antispam) mod for Ryan’s original form.
What I’ve added (here’s where the “III” comes in..) is giving your visitors the option to specify the subject of their email, and proper, valid xhtml.
The look and feel of the form is easy to customize by creating a file called mystyle.css and upload to the contact form’s directory

The form doesn’t work on Yahoo! hosting, don’t ask me why, ask them..
If you have trouble inserting the contact form in a page or post try to use code view
If this wasn’t the contact form you were looking for there’s like <a href="https://wordpress.org/extend/plugins/search.php?q=contact+form" rel="ugc">ten thousand others</a> around so at least one of them have to fit your needs.
The antispam question doesn’t protect you againts human spammers, only spambots (unless you come up with a brilliant but easy question like the question that gives the answer to life, the universe and everything)
