I never tried this plugin. But remember that this is a very old plugin, so it could have problems with the new plugin interface.
Note: A extremely similar plugin can be found in this thread:
http://shoutbox.menthix.net/showthread.php?tid=17934 (old version (1.2) with installer)
http://shoutbox.menthix.net/showthread.php?tid=17...d=196491#pid196491 (recommanded, "latest" version (2.0), but without the installer)
note that this is also an "old" plugin, but it's an alternative, so, you never know...
