Tell President Obama What's On Your Mind

At 4pm et today, President Obama will be having a live Town Hall -- with YOU. Is there anything you want to say to him? Anything you want to ask? Whether it's about the economy, Afghanistan, the environment, gay rights, health care, college money, your school and your teachers, bullying... whatever's on your mind, we want to know about it. And MTV News wants to let President Obama know, too.
