EtherPad

We love this live collaborative editor and use it all the time. Wouldn't it be awesome if you could edit Wagn cards live with other people?

EtherPad.com was bought by Google in March 2008, and the code was made open-source under a free, open-source licens. EtherPad.com stopped allowing new pad creation. Development continues at http://etherpad.org/ and there are a number of sites offering EtherPad as a service.
