Hiya Tim,
Great work with this package.

I am just working with this and have a suggestion to update jQuery.validate to include some custom error messages and for the comment field to require a minimum of 10 characters.

For example:

jQuery("form").validate({
                rules: {
                    comment: {
                        required: true,
                        minlength: 10
                        }
                },
                messages: {
                    name: "Please enter your name",
                    email: {
                        required: "Please enter an email address",
                        email: "Please enter a valid email address"
                    },
                    url: "Please enter a valid URL including http://",
                    comment: {
                        required: "Please enter a comment",
                        minlength: "Your comment must be at least 10 characters long"
                    }
                },
                submitHandler: function(form) {
                    //Usual code carries on as normal...
