Let's change Yahoo Mail

Do you want to add new innovative services to your Yahoo Mail? Now you can!
Yahoo is planning to release the code for its Yahoo Mail software in order to encourage software developers to build new applications based on e-mail.

This move is based on the success of initiatives of open software like Google Maps and Yahoo's Flickr, which inspired a new wave of programming where the client users are the developers of "extensions" to the original software.
