There is a new link beside the Web History one on the iGoogle Bar: Preferences.
google.com/ig/settings

It allows you to edit yours tabs, but I've remarked there's already an error: I have a tab called 'name this tab'.

My intuition says it's the default iGoogle homepage, that Google offers you to edit when adding a gadget ("also add this when visiting google.com?)

iGoogle is slowing becoming a Facebook-like (see the new Form gadget!). That's cool

I also have a "Name this tab" which doesn't exist. I also have gadgets listed that are on other tabs, I can't set my country as UK and you can't change to the four column layout.

Also, Google refuses to acknowledge that it supports postcodes in the UK for weather on SERPS instead listing a few citys miles from where I live.

Overall, not a great feature rollout.

All they need on that page now is a way to drag and drop the tab names on the left hand side so that we can organize them any way we want. :)

The link has disappeared from my iGoogle. A short-life feature...
That could be added to "The Lost Features of Google" post by Philipp ;-)

The link can still be found under the MY ACCOUNT page. There is a 'settings' link next to iGoogle on that page.
