Ok.

I think I still haven't managed to explain what I mean

1. I have all registered users permitted to use the chat.
2. I have turned on module implementation.
3. I have created a page in joomla and a menu item that only super users can see. I have included the chat module in this page. This means that this page is only accessible by super users.

However. I can see all registered users in the chat although there is no way they can access the chat (as explained in step 3 above). This proves that all permitted users (registered users in my case) are logged in the chat and are shown to be active in the chat no matter if they clicked on chat menu item or not.

What I want is only those users that click on menu item chat to be shown as active in chat.
