This module allows after a certain time a popup window (or a div layer) to appear asking if live chat is needed.

The HTML can be fully customized to suite your needs. I tested it with Meebo and it worked with not much fiddling. You can also set up a link that activates the script.

I find this module useful but it appears to be not very intuitive and user friendly despite the creators' explications.

Thanks to the programmers for this useful module!
