This is a very nice addon however it could be better. This is my feedback:

• When you install this it's disabled by default in the user control panel. What's the point of installing this if it's going to be disabled by default for all users? You should change that behavior.

• Also you should include a close icon button in the corner of the notification box ("X") so when you close the box then it doesn't appear anymore unless there is a new notification.

• There should be an option (disabled by default) so members could choose if they want to hear the sound or not.

• This mod appears to be looking for an image from images/misc/blinkpm.gif however that GIF isn't part of the stock vBulletin so maybe you should include the icon in your package?

Can't seem to get this puppy to work. I have the Live Thread installed and it's working perfect so I know the AJAX is capable.

I followed the instructions and used both the UTP-8 and Windows products (switching back and forth when testing) and could not get it to work correctly.
