Check out google's source code...
in the body tag..
onLoad="var SymTmpWinOpen = window.open; window.open = SymWinOpen; sf();
the sf(); function is the one you want
function sf(){document.f.q.focus();}
'f' being the form name and 'q' being the name of the input box
Does anyone know how I make the page center (or at least scroll so that the box is in the viewable window)
Im guessing by this you mean the user has to scroll down the page to veiw the form??
If thats the case, use ananchor
