Gary,

The source is available in a big tarball. I've expanded this out at http://www.bleb.org/software/n800/os2007-src/ . The only public core Subversion repository is at https://stage.maemo.org/svn/maemo/ .

Patches to Subversion or any of the internal applications should presumably be raised in Bugzilla.

In particular, for the RSS Reader, see https://bugs.maemo.org/show_bug.cgi?id=953

It's probably worth a mail to maemo-developers too, to ensure no-one else is hacking on the same thing as you.

HTH,

Andrew
