You often get e-mails from friends about some topic asking you to sign a petition online at http://www.petitiononline.com ... For example, "Support Anna Hazare by signing petition online at petitiononline.com" and so on. There are tons of such petitions at this site.

And a lot of people around the world actually spend time thinking they contribute for a cause.

I just wanna know how that site works and do they actually forward such petitions to respective concerned bodies?
