Form field Progress Bar © JavaScriptBank.comSimilar in function to Form Field Limiter, this JavaScript allows you to restrict the number of characters inside a form element (ie: textarea) while displaying a progress bar on the remaining characters beneath it. Very cool, and works in IE4+, NS6+, and Opera 7+.
