// **My2Cents** is a campaign widget for calling elected
// representatives. Source is available on
// [GitHub](https://github.com/affinitybridge/my2cents).

// My2Cents is built on [Express](http://expressjs.com/). It uses the
// [Twilio API](http://twilio.com) to make phone calls and the
// [Open North Represent API](http://represent.opennorth.ca/) to receive
// representative information. [Jade](http://jade-lang.com/) is used for templating and
// [Stylus](http://learnboost.github.com/stylus/) helps with CSS.
