 //the Sliding Tabs mootools plugin is a creation of Jenna �??Blueberry�?� Fox!
// Jenna released it under a donationware license on the 7th of December �??07
// Use of sliding Tabs for more than evaluation requires donation unless you
// really cannot afford a couple of bucks. Regardless, I'd like to know where
// the script gets used! My email address is at http://creativepony.com/#contact
