What is GHOP? According to their website:

Following on from the success of the Google Summer of Code program, Google is holding a contest for pre-university students (e.g., high school and secondary school students) with the aim of encouraging young people to participate in open source. We will work with ten open source organizations for this pilot effort, each of whom will provide a list of tasks to be completed by student contestants. Tasks can be anything a project needs help with, from bug fixes to writing documentation to user experience research.

I am working on one of the Drupal tasks (#68, a documentation task) right now and am enjoying it. Don’t wait! You can’t claim any more tasks after January 22, 2008, 12:00 AM Pacific Time.
