Help needed developing Logic!

Hi, I've made a PHP Chatroom and i need help developing the logic behind the "Private Chat" feature. I'll first explain briefly how my chat works. It's a very very simple Chat using just DB and nothing else. User enters.. his name,date goes into Chat. QueryString passes his name to main area from where he can post messages with the name as the main link between his messages & database. You can view it at http://www.mjimm.com/index.php3?page=chat/mjchat.html Please choose "PHP Chat" from above link. Anyway, now i need to develop a system where one can private chat with a user. So that by selecting the User's name, when the person sends a message.. it is displayed only on the Selected User's chat.. and not anyone else.. or perhaps some other way. Can anyone help? Ask me any question if you wish to clarify further how my chat works!! Cheers & Glory, T. Edison jr. ===== Rahul S.
