Problem Definition Basic features of instant messenger Create account and login Send and receive messages See when contacts are online Add a contact to Friends List Change display name Logout

Analysis: 

Analysis Feasibility Analysis Investigated group’s ability to : Communicate via internet Windows Sockets User Datagram Protocol (UDP) Develop a windows environment application Coding: Microsoft Visual Basic 6.0 Graphics: Adobe Photoshop 7.0
