Chat Program - CSocket

Ok, I need a Chat Program to run on the school computers. I was planning on running the Server on my Computer, as its already has the Vb Runtimes installed, and maybe writing the Client apps in VBA.

But I'm having alot of trouble with it and I was wondering if anyone could get the app to do the following.

At the moment when the user connects to the program, it shows the IP address and when they chat is shows the IP Address. I would prefer that it would say a name which the User enters.

The server needs to be able to handle at least .... 26 computers... although I don't think this should be a big problem.

I need tgo use CSocket, not Winsock, which can be downloaded from
CSocket.

All I need is the ability to hide the IP Address and hopefully the Server can easly be modified to act as a Client. I've posted the example I've been using.

Thanks in advance. :D
