dianovo is a relatively new site for green-minded social networking. For Valentine’s Day, they are planting one tree for every ‘eco-valentine’ sent from their site from now until Valentine’s Day. There is a small catch – basically site membership. You have to be a member to send and the e-card needs to result in a new member, but I think the few minutes it takes to sign up are worth getting a tree planted. And by ‘few minutes’ I do mean that – their sign-up involves writing about how you are or are planning on living greener, etc. I haven’t spent too much time at the site, but I like the premise.

Send an e-card and plant a tree!
