An instant messaging client application is provided that receives requests to initiate instant messaging conversations and, in response to the requests, displays a notification window. The notification window includes information that may allow a user to decide whether or not the user would like to participate in the instant messaging conversation. The notification window is displayed gradually and removed gradually. The notification window contains an indication that another instant messaging user would like to initiate an instant messaging conversation and may include an identification of the remote user. The notification window also contains a description of the topic for the requested instant messaging conversation. The instant messaging client application may also display a notification window each time an instant message is received from a remote user and the application window is in a non-visible or non-active window.
