Multi-Threaded Socket programming using C# : first step for a chat application

Just arranged some code to create a server and a client application that can talk over separate threads. The code  is not that efficient, yet, the programs can be used as the very basic for writing your own chat servers and clients (I din try though :P)

Download and play with the code by yourself and feel free to comment.
[The code is in VB.Net; I'm no more a VB coder though :S I had to prepare it for one of my cousins.]
