Cheers it seems to be just what I need , I have it using growlnotify to alert me in Growl For Windows in Parallels on my Mac, then forwarding it to Growl on my Mac as WLM alternatives are so bad for OSX.
But do you know if it would be possible to make it so that it sends the contact name to the command script so I can see who is signing in, and also add support for other events, such as a new message?
If so could you point me in the right direction into adding this in?
