Reed Elsevier website

Today I went to Eywitness to take part in a usability test of Reed Elsevier website. They gave me a few senarios, each consisted of a few tasks and demanded me to fulfill them while thinking aloud. As compensation for the time of the participants, they agreed to pay some money to a charity chosen by the participants. I asked them to pay some money for Niger's famin. It was a good experience for me as it was the first usability test I participated. I got some ideas how to conduct a website usability test.
