If you're wondering how to access the settings page from iGoogle, click on the small arrow displayed next to the name of the current tab and select "Edit this tab". The settings page is also the place where you can select your location, choose to automatically open links in a new tab, change the name and the layout of a tab or backup the iGoogle page. Oh, and don't forget to click on the barely noticeable Save button every time you change the settings of a tab.
It's amazing to see how simple and intuitive Netvibes' interface can be: the tabs can be reordered using drag and drop, tab names can be changed using a simple click and switching between different tabs doesn't reload the page. iGoogle still has a lot to learn from Netvibes in terms of user friendliness.
