Text messages driving activism at concerts

Coldplay is also joining the club of good music Samaritans. Apparently, Oxfam International will let Coldplay fans text to sign a petition advocating changes in trade laws.
Before the concert, Oxfam will show a video featuring Chris Martin, Coldplay's lead singer and an Oxfam spokesman, and the international anti-poverty organisation will encourage concert-goers to sign onto Oxfam's Big Noise petition by immediately texting their e-mail addresses to "TRADE" (87233) on their cell phones.
