Print ONE copy of anything, and then take it elsewhere to have it copied. No games of any kind once the lab is half full. If for any reason a lab consultant or a staff member asks you to stop playing, stop. Even if you do not fall under the above criteria. If the last name is longer than 7 characters, the username is the first 7 characters of the last name followed by the first initial.
Some exceptions exist.
If you have problems, see a lab monitor. Hit that button with the left mouse button. A confirmation box will pop up. The best way to learn the windows is to play with them. Log in and have fun, but do remember that any modifications you make are not supported by site.
