So maybe you want an email subscription to svn changes from a project in Google Code. But Google Code only lets you set up one email address to receive such changes (basically inheriting this limited configuration from svn). Sure, you could set up a listserv (or even a Google Group) and send it there. But this is a pain. We don’t like pain.
Or, you could realize that Google Code also offers Atom feeds for the list of code changes, as well as some other useful things. http://code.google.com/p/your-project-name/feeds (thanks David Walker for pointing this out). Maybe you’re happy getting them in Atom.
But maybe you still want it in email. No problem, use http://www.rssfwd.com/ to forward an RSS or atom feed to your email.
