A couple days ago MSN blogged Come Visit the MSN Search Team where they are inviting you to fill out an application. They will review all applications submitted and then invite those who they feel most qualified, to a fully paid trip to Microsoft's HQ in Washington. Last Search Champs was invite only back in March 05.
