How do i make a username string get sent to server? NetworkView

Ok, so.. I'm trying to make a multiplayer game with NetworkView. Ive got the connection working from Client to Server. As you can see here... its written in C#

Now what you see here is 'Player 0'. The way ive achieved that is by

 public int playerCount = 0;
     
      void OnPlayerConnected (NetworkPlayer player) {
             
             PlayerLog.PlayerListAddEvent ("Player " + playerCount);
             
             eventLog.AddEvent ("Player " + playerCount + " - " + "Connected from " + "'" + player.ipAddress + ":" + player.port + "'!");
         }

but id like the '0' to be the players name.. :( i cant do it! I know i have to use RPC.. but can someone get me started?

i have three scripts. Server, Connect, and Player

Server is obviously the server controls; Connect how you connect to the server; and Player is what spawns when you connect to the server.

Now in Player i have put the OnGUI function to bring up a textbox which you can write your name in and set. but how do i get it to the server?

     public static string myUserName = "";
     
 
     void OnGUI () {
         myUserName = GUI.TextField(new Rect(Screen.width / 2 - 100,Screen.height / 2 - 25 , 200, 20), myUserName, 20);
 
     }
