Poll Everywhere

I recently learned about a new Web 2.0 tool called Poll Everywhere. I'm planning on integrating it into one of my online classes...so started playing with it a bit! Teachers could actually have their students answer a question via text messaging with their cell phone. Instantly, a bar graph will appear to show the results. This could also be a great way to engage adult learners and high school students.

Could you help me test this out? Basically you will text a message to 99503. Then in the message, you will type the number that correlates with the response you want to choose. Please help me out by answering this question via your phone!
