MUD/MUE Programming Team..

I am working on a project, creating a very basic MUD/MUE engine.  It is written in C++, optimized for RH5 Linux.  

I am working on it with a friend of mine, we are both C++ Analyst programmers.  We could really use some help from an experienced network programmer.  Anyone out there and look for a fun project to help out with?

Also, I've run into a bit of a theory problem.  I'm sure it works, I just can't understand how.

Say you have a client server application, Joe logs onto the server, and it creates an instance of the class CURRENT_LOGGED_ON_MEMBER.  Then John logs on and it creates another instance of the same class, but with John's information in it.  The class is just serving a big doubly linked list.

Is there any way I can create a pointer that will always point to Joe?  Or everytime I want to do something involving accessing Joe's data, do I have to run through the whole linked list until I find Joe's specific one?  Is there an easier way to do this?  Involving something other than classes/structs/linked lists?

Thanks! I'm really lost,
