The more people that sign your petition, the higher chance of success it has. It's essential the people signing your petition tap their personal networks and recruit friends to sign as well. If a person activates their account after signing a petition, or signs in with Facebook or Twitter, they will have their own personal recruiter link (shown below) which they can use to get credit for all the recruits they bring. Using a Leaderboard, you can encourage your most ardent supports to try and get to the top.
