Scenario 1

A product I love is BurdaStyle.

####Features To Add

  • Premium email newsletter subscription that comes with a few simple patterns and articles about techniques.

    This European based company publishes a magazine multiple times a year with very limited distribution in the US. non-European customers can subscribe to the US version of the magazine but it's expensive and orders take a long time to process.

Initialize a bootstrap modal with a form which submits with ajax. This is my first foray using JQuery's widget factory: http://learn.jquery.com/jquery-ui/widget-factory/how-to-use-the-widget-factory/
// Dependent on twitter bootstrap's modal plugin
// Per Bootstrap's api, link to trigger modal should have a data-toggle="modal" attribute
// Modal markup should have one form element
// Initializes with the link or button element which opens the modal
// $("#my-button-element").ajaxModalForm({success: someSuccessFunction, error: someErrorFunction});
$.widget("myNamespace.ajaxModalForm", {
_create: function(){
this.$form = this.element.find("form");
