The group chat feature lets you chat with many friends at once. There's no limit to the number of people you can chat with, and any participant can invite others to join. To get started, follow these steps:
Start a chat with a single person in your Contacts list.
Once you've started the chat, click Options at the bottom left of your chat window and select Group Chat.
In the field labeled 'Add a person to this chat,' enter the name of the contact(s) you want to add to your group chat.
To end your chat, click the X at the corner of the chat window. Others in the group chat will get a message saying that you've left the conversation. If you want to rejoin, you'll need to be invited back by a contact who's still in the group chat. The group chat will continue until all participants have left.
