JQuery :: Validate And Submit - No Page Refresh

I am trying to find a particular tutorial on the web that I used to create a REALLY simple script that made use of jquery.form and jquery.validate.

The script would use the simple validate command to validate inline, then when submitted, a loading graphic would appear, call upon the php script referenced in the form action, process, then spit out a message on the same page without any refresh.

I have a few questions about modifying it..

Here's the script.. noting that Im also calling jquery.validate and jquery.form:

I would like to have the message that appears, to fade out after being displayed for 5 seconds. I don't know how or where to add the fadeout command in the function above.
