This Meebo Chatbox is configured inside a Conduit Toolbar (OUR QUICKSEARCH CMB LIBRARY TOOLBAR) as a floating window. It stays available no matter where you go.
You can even drag it to the side of your screen, whatever you want. It only disappears when you click the X.
This way the user can -while chatting with a Librarian- follow his instructions directly and without having to switchs screens. Websites can be visited, settings adjusted, searches analysed, and you will have the chatbox visible all the time!
