I suggest, in addition to the Motorola Q site, that you use the user generated Wiki, moderated by Motorola at: http://www.motoqwiki.com

It is very well done and a useful resource.

I used the Resco reg editor (installed from my PC) and deleted the registry entry for a startup sound, and it worked fine !! Now I can leave my notifications intact, and not have to put up with the annoying sound each time I start the Q (such as after having turned it of as required in a plane). Thanks for the tip !
