-This plugin is used to play sounds (currently a WAV file) through the
-browser whenever the user has unseen messages flagged in the left window
-pane. There are options available (on the options page of course) to
-disable this feature for each user, and to select different media files
-from the users local computer. The default is that this is NOT enabled,
-so you'll need to go to the options menu to turn it on first! There are
-also options to show a popup window via JavaScript.
