Any reason why I wouldn't want to use AJAX to retrieve info from the
DB without reloading the page?

Keep in mind: My goal is (and has been) to change only the templates
without touching CGI or PM files.

Somebody at work suggested AJAX can be implemented in the knob
template to retrieve a list of users in specific groups without
reloading the page. This would be used to display only certain users
depending on the status.

Thanks for any feedback!
