How can I change my gmail from appearing on my igoogle page?

I want my yahoo email to appear on the top of my igoogle page instead of my gmail. I already tried unchecking the box on my gmail notifier but it won't chamge can you please HELP!!! THANX!|||Probably you can't see yahoo mail directly on igoogle, if you use my yahoo page you will be able to do that and at the same time have the ad-on on your web browser to search on google if you prefer that search engine.
