Once you enter the details and hit "send" you get a confirmation popup at the top of the screen that says "message has been sent". However, after this popup goes away, all the fields in the form still contain your info and the captcha field is blank. If you didn't catch the "message has been sent" popup, you might think that you entered the captcha phrase wrong and need to try again.
I'd like to have the confirmation message stay on the screen longer so the user knows the message was sent. Even better would be able to have the Contact Us form appear as a popup on my home page like it does if you were on a forum page when you clicked the link.
