Thanks very much for your help Jan, I gathered and took into account previously what you said. I believe the chat system uses their password, as it is taken directly straight out of the user table. It would just be nice though to generally hide these things, I know there is ways and means around everything, however trying to prevent something will always help in the long run and make things more difficult, especially for new peeps. It's just for my Administrators it would make life more easier if there was say a checkbox to prevent access for guests to X resource or feature. - What they dont know wont hurt them 
. I have other methods after that to stop them dead in their tracks, its more for functionality purposes, so peeps know what they are allowed access to and are not
Many Thanks,
Josh Coombs
