its to verify that you are the owner of that heatware account. cuz i saw that all the trades shown under dng29 were in the anandtech forum. so a scammer might copy that name in a forum which it hasnt been registered. then try to claim that it is his heatware when "selling". its also good a good...
add your name 'dng29' next to techpowerup in the aliases section of heatware. look up bcracer220 if you are wondering what the aliases section looks like.
