Amnesty International has launched a new method to collect digital signatures, called Twignature, which has been created by BMF Melbourne. Twignature works by converting Twitter users’ names into a digital signature when they retweet a message from Amnesty International. The instant conversion enables Twitter users to add their digital signature to online petitions whilst also promoting the cause across socialmedia.
