The be honest, online petitions are wasted energy. They do nothing more than get a bunch of people to sign something that'll never work out in the end.
So, what do you do? Well, you get PEOPLE who are being directly impacted by something to send a letter. The letter says that you cared enough to write in and say hey: stop it, help out, do something, take action.
You want something done? Write a letter. Send an email. They don't care about online petitions.
Just take a look at the numerous Xena movie petitions out there. Has it helped it any??? The answer is NO. It hasn't.
