I'm going to chime in here with ninth_wave...I agree to leave well enough alone. Auctiva does it's maintenence at the same time Ebay does theirs which is late at night in some parts of the U.S. (Midnight and on, where I am) Have you ever logged into Ebay at this time and seen those annoying little banners 'some of your information is missing at this time'? The way this is set up now is no accident. As has been said before, no matter what time maintenence occurs it will affect someone somewhere.
BTW ninth, if you ever need a whack on the head just ask
