Largest Money Raise For Epilepsy.

Epilepsy BuskerFest is the Largest Money Raise in the world.

Last year we raised $75 000 dollars. I'm trying to increase that number, we need to get more "Likes" and "Shares" to be more noticed.

Can anyone give me a hint how to get more "Likes" and "Shares"? In https://www.facebook.com/BuskerFestVolunteers
