Stephen Samuel's Journal: OS authors need to register their copyrights.

This article from lawyers.com indicates the necessity of Open Source authors registering their copyrights if they wish to have maximal rights to enforce their GPL copyrigts. Apparently, collective copyrights (i.e. on a magazine, or Linux) would not constitute a proper registration of the constituant parts (e.g. A single magazine article or Kernel module).

If people want to hang SCO by the balls, then we'll need to register the copyrights on our many versions of software -- and this would include deriviative copies as separate entities.
