Hi, I found this script in one of unity demo projects...

    GUI.FocusControl("Chat input field");
}

function OnGUI ()
{
    GUI.skin = skin;

    //if (GUILayout.Button(showChat ? "Hide Chat" : "Display Chat"))
    if (GUI.Button(new Rect(Screen.width-100, Screen.height-30, 90, 20), showChat ? "Hide Chat" : "Display Chat"))
    {
        // Focus first element
        if (showChat)
        {   
            CloseChatWindow ();
        }
        else
        {
            showChat = true;
            FocusControl();
        }
    }

    if (showChat)
        window = GUI.Window (1, window, GlobalChatWindow, "Chat");
}

function GlobalChatWindow (id : int) {

    var closeButtonStyle = GUI.skin.GetStyle("close_button");
    if (GUI.Button(Rect (4, 4, closeButtonStyle.normal.background.width, closeButtonStyle.normal.background.height), "", "close_button"))
    {
        CloseChatWindow();
    }

    // Begin a scroll view. All rects are calculated automatically - 
    // it will use up any available screen space and make sure contents flow correctly.
    // This is kept small with the last two parameters to force scrollbars to appear.
    scrollPosition = GUILayout.BeginScrollView (scrollPosition);

    for (var entry : ChatEntry in entries)
    {
        GUILayout.BeginHorizontal();
        if (!entry.mine)
        {
            GUILayout.FlexibleSpace ();
            GUILayout.Label (entry.text, "chat_rightaligned");
        }
        else
        {
            GUILayout.Label (entry.text, "chat_leftaligned");
            GUILayout.FlexibleSpace ();
        }

        GUILayout.EndHorizontal();
        GUILayout.Space(3);

    }
    // End the scrollview we began above.
    GUILayout.EndScrollView ();

    if (Event.current.type == EventType.keyDown && Event.current.character == "
" && inputField.Length > 0)
    {
        //@TODO: This should be dependent on who actually sent the message
        //var mine = entries.Count % 2 == 0;
        ApplyGlobalChatText(inputField, 1);
        networkView.RPC("ApplyGlobalChatText", RPCMode.Others, inputField, 0);
        inputField = "";
    }
    GUI.SetNextControlName("Chat input field");
    inputField = GUILayout.TextField(inputField);

    GUI.DragWindow();
}

@RPC
function ApplyGlobalChatText (str : String, mine : int)
{
    var entry = new ChatEntry();
    entry.sender = "Not implemented";
    entry.text = str;
    if (mine == 1) entry.mine = true;
    else entry.mine = false;

    entries.Add(entry);

    if (entries.Count > 50)
        entries.RemoveAt(0);

    scrollPosition.y = 1000000; 
}

Don't know how to use it or apply it yet... Can someone please help?

I believe you are talking about the Chat folder in Networking.zip that's out there in http://unity3d.com/support/resources/example-projects/networking-example

This folder comes with a demo scene called "test". If you open that, it'll tell you how this chat script is used. Essentially, you need an empty gameobject with this script added and with NetworkView. Create another empty gameobject with ConnectGUI script for initiating server/client. And you are good to go with a chat scene (using Unity's in-built networking; I'm assuming you've a PRO or 30 day license.)
