THINGS YOU SHOULD KNOW ABOUT CHAT ROOMS (continued)
Some chat systems allow you to archive online discussions for review by those not present or for closer analysis at a later date. This practice is recommended for hosted sessions.

Some chat systems are memory-intensive and may be slow in loading or completely crash a computer system. The CourseInfo system used at Virginia Tech has had reported problems in the past, with only small numbers of students (e.g., 4-5) able to communicate at any one time. Make sure you test out any chat system for speed and robustness prior to engaging in scheduled classroom activities.
Abuses of chat rooms are common, from inappropriate language and conversations to cyber-stalking. Make sure any young or immature students are aware of the risks and responsibilities.
