I don’t have it running since I am trying to hack it a bit but, currently you have to be logged in to see it. That’s what I’m working on, at least the who’s online part.
What it does is show you who is on the site and who is on each page with the opportunity to initiate a chat with them. I’m trying to figure a way for it to give access to level 0 users with a random user name such as Guest 121. Other than that it is ideal for me on my business site. Private notes is what I use for a Help Desk. I can save all notes and add extra info when needed.
Hope that helps.. BTW with XDTalk sometime the database does not populate. I posted the MySql on NeverLand’s site if you run into that problem.
