Jules has walked away from a lab computer without logging off. Trish

sits down and, still logged in as Jules, sends inflammatory e-mail

messages out to several students and posts similar messages on the class

newsgroup.

It seems like every time Melanie logs on to her account, Stanley knows

about it and sends messages that cover her screen with text. At first,

she thinks it is funny, but now it's really starting to bother her. The

messages reformat the text on her screen and, besides, its kind of

creepy the way he always knows she's logged on.

Marla figures out that when she is logged into the server, she can look

at others' directories, make copies of files, and deposit new files. The

operating system was designed to allow this functionality so that

people could share their work. Mr. Klausinsky objects when he observes

Marla poking around in another student's directory. But Marla responds

by saying, "If the system allows me to do it and there's no specific

rule against it, what's the problem?"

Russ has been an active participant at a chat site for teens. He knows a

few of the people in "real life," but many live in other cities. One of

them, Stuart, will be coming through town in a few weeks and wants to

get together. He asks Russ for his home phone number and address. Russ

suggests that they just meet at the mall, and Stuart agrees but wants

Russ's home info anyway in case he's delayed.
