You know that you can apply any sound for almost everything regardless whether you use a theme or not. Just put some wav-files you like in C:\Windows\Media and configure your soundscheme in controlpanel - sounds. I personally don't like my computer making noise all the time. It just says in a nice (female) voice hello and goodbye when I start and shutdown.
To find sounds you can try as an example http://www.findsounds.com/
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
