Some people say once you go to igoogle.com and start personalizing a google page then you can't get to plain google by clicking on your home page any more. Well I figured a way around it.
Type this in for your home page: http://www.google.com/url?sa=p&pref=ig&pval=1&q=/webhp
Then when you go to the home page it will be go straight to the classic home instead of going to igoogle.com. Have a great day.
