Make the Tracker Private?

[Cyber14]

Hello, my name is Cyber14 and new with Trackers.

I'm working with TT v2.06 and my question is: Can i make everything Private?

I want to have a private tracker for only friends and users that are been invited for my tracker.

Now i see the Blocks and other things sutch as the Index, Notice, News, and many more.

But i'm looking for something that only shows:
You are not logt in to this tracker.

Can somebody help me with this?

It have been solved!

Index.php

require_once("backend/functions.php");
dbconn(true);

Add loggedinonly();

require_once("backend/functions.php");
dbconn(true);
loggedinonly();

This is the way that i have solved my question.
