Receiving a Chat Invitation
You can invite your Buddies to a chat room, and they can also send you invitations to join them in chat rooms.
When you receive a Chat Invitation, you can:
Accept the Chat Invitation, by clicking Accept.
Warn the user who is sending you the Chat Invitation by clicking Warn if you don't want to accept it. Clicking Cancel also rejects a Chat Invitation.
Display information about the user if you don't know who is sending the Chat Invitation by clicking Info.
Send an Instant Message to the user sending the Chat Invitation by clicking IM. Sending an Instant Message is good if you want to know about the chat discussion or know of other users who are participating in the discussion before joining it.
