First, if this isn't the right area, I apologize.
What I am trying to do is setup a support site, basically my site members are employees, visitors won't register. I am trying to find a way to show users online staff, which i've done using member lists, when the user clicks a member they are taken to the profile, I need to add a way to chat with the staff from their profile. Is there an addon which will add a "chat" function to users profiles?
If not, how can I add in html, where I can add my own "chat" function using third party tools?
