206478 Private Chat

I am currently using PHP Free Chat, and need to make some changes to it. The end goal, is a function similar to Google Talk. Task: 1) Create a list of people online, for a general room 2) Create a "chat with me" icon" that a member can click on to initiate a chat with another member. This is not a communical chat area, only private chatting. If you would like clarification, please let me know. I am not married to PHP Free Chat, if you have a better alternative, please feel free to make a suggestion.
