If you're one of the lucky few going to Cop15, the most important climate-change summit since Kyoto and ideally the one that will save the world, then thank your lucky stars. If you are not, you can at least try to be heard in other ways.One innovative way is the Guardian's A Message to Copenhagen Flickr page. It launched today and will collect and run user-submitted images that send a message to the delegates who'll be attending the conference. Will they look at these pictures? Who knows, but lots of other people will. It just started so there are not a ton on there yet, but we're still a few months out. I imagine they'll get cooler as time goes on.What do you want to say?
