This is amazing, seeing how many people can do things at work. Where I work they are extremely strict about the Internet only being used for work-related things, with firewalls and blocks to keep out most popular sites, including Yahoo, Hotmail, Amazon and Ebay. They also print out lists of Internet Sites visited, with inappropriate ones highlighted, and send that to supervisors. Needless to say, all my ENWorld visits are from home.
One of the players in my group was an I.T. tech, and he used to send out at least 10 e-mails a day to the group from work with various things (mostly jokes) he found on the Internet. We commented about how it seemed like he never did any actual work. His employer must have thought the same, as he got laid off. He now works in the I.T. Dept. of my employer, and we now only average about 2 joke e-mails a week from him, all sent from his home.
