Resistbot

Text RESIST to 50409 to contact your officials

This is by far the coolest / best / most helpful chatbot out there, and it's using SMS to do it! Resistbot helps you contact your Senators— you send a text, their office gets a fax! It's practically magic, and I'm obsessed.

Magic seams pretty darn perfect for this. Text to get seemingly anything you need. I just wish it was available in the UK ;)
