I created a page using the Contact Us shortcode/feature in the latest beta of TT. I wrote it as such:
Please use the form below to contact me.
When I view the page it puts the contact form before the "Please use the form below to contact me." text. In other contact pages I've used with a shortcode it puts the text in order. That is, any text before the shortcode goes before the form. Any text below/after the shortcode shows up after the form.
