Some of the most popular 3D chat experiences are IMVU and Second Life (though they extend far beyond just chat).

Many such implementations generate profit by selling virtual goods to users at a high margin. Chat rooms, particularly those intended for children, usually have rules that they require users to follow.

For example, as illustrated above, the "(40)" next to the Actors & Actresses chat room title indicates it had 40 users in the chat room.7.

The primary use of a chat room is to share information via text with a group of other users.

Generally speaking, the ability to converse with multiple people in the same conversation differentiates chat rooms from instant messaging programs, which are more typically designed for one-to-one communication.

These are characterized by using a graphic representation of the user, an avatar (virtualing elements such as games (in particular massively multiplayer online games) and educational material most often developed by individual site owners, who in general are simply more advanced users of the systems.

The most popular environments, such as The Palace, also allow users to create or build their own spaces.

Typing with caps lock on is usually considered shouting (suggesting anger) and is discouraged.

Offenders of these rules can be "kicked" (temporarily ejected from the room, but allowed back in) or banned completely either on a temporary or permanent basis.

Some online chat rooms also incorporate audio and video communications, so that users may actually see and hear each other. These are typically implemented by an external process such as an IRC bot joining the room to conduct the game. The rules are generally posted before entry, either on a web page or an MOTD-type banner in the case of IRC and other text-based chat systems.
