This is what Change.org says we need to do: Ask signers to get involved In addition to posting updates on your petition page, ask your signers to share your petition with their friends. Just imagine how fast you can grow your campaign if each person who signed your petition passes it on to three, four or even five others. Your decision maker will really take notice! Here are some other ways your supporters can help: Share. Ask supporters to email five of their friends with a link to the petition, or use Facebook's share tools to post on their walls. Spread the word. Do your supporters have personal ties to the issue? Ask them to post their stories on their Tumblrs or blogs. Show up. Invite supporters to a petition delivery, rally or event about your campaign.
