For my Information Technology class I have to post a review of "challenges" that test your internet knowledge. 

They are at: http://21cif.imsa.edu/tutorials/challenge/Q2Q/KeywordChallenge.swf 

I did the "Great Wall Challenge", and the "Stamp Collectors Challenge both gave information which is meant to help people use and understand internet searches.

I personally found them to be boring and dull, but they could be helpful for some people.
