// Business Catalyst Blog Dates customizer
// Based on JQuery 1.4.2
// By Nelson Ho based on the work of Chris Matthias (chris@boldcode.com)


// This plugin takes one arguments;  true or false for "noStrings".  If you'd like to replace the month strings like "Feb" with "02" just pass in true. See usage below
// Most Business Catalyst installs will use the following selector: ".blogsitesummary span.date" but this should work for any parent element that contains a date with the format dd-mm-yyy.

// Usage Example:  $(".blogsitesummary span.date").bcBlogDates();
// Usage Example with no strings: $(".blogsitesummary span.date").bcBlogDates(true);

//indexOf on a Javascript array does not work in IE
//snippet source:http://www.pearweb.com/javascript/array-index-of.html
