Google has just announced that it is offering a free, online, community-based
course on how to become a power searcher. Upon passing the post-course
assessment, a printable Certificate of Completion will be emailed to you. It
is not clear whether this is a once-off or will be continuing but seeing
registration is required I suggest you hop in and register ASAP. Imagine
being a "Certified Google Power Searcher", how cool is that?
