Instant messaging (IM) is an easy way to stay in touch without having to wait for email responses. Users type a message and click "send." That message instantly appears on another person's screen wherever he or she happens to be.

Users can exchange instant messages...

• on computers and mobile phones or
• between computers and mobile phones or
• any other Internet-connected devices.

As great as it is, IM can be dangerous. Like chatrooms, users need to be careful about whom they IM with and what they type.

Some instant messaging software can be used to send pictures — in real time — along with text. Users must be careful about their privacy and protecting it.

Some services encourage users to post a “profile” with information such as...

• age,
• sex,
• hobbies, and
• interests.

These profiles can help users meet similar people, but they can also make them the subject of harassment, even if they don’t post their name and address or other information.

If users don’t have a public profile, they’ll be safer and avoid a lot of hassles.
