Lots of us have experienced the many challenges that come with being a girl in sports. Gamechangers wants to call out those challenges and find solutions to solve them. But they need your help.

Gamechangers teamed up with Nike to create an online, interactive forum that encourages collaboration and discussion, along with competition, to draw out the most effective ideas for changing things up.

If you have an idea for how to use sports to enact positive change in girl's lives, now is the time to speak up. Even if you don't have an idea, you can get involved and share your opinion. Join the online Gamechangers community to tell us what you're thinking, how you see the field, where its challenges and opportunities lie. And in March, you can help vote on a winner.

Sports have been such a positive influence in my life that I wish everyone could experience it. Maybe you have a similar experience and a suggestion for how to share it with the world. Speak up and change the game.
