Navigation is now much simpler.

The site network menu (Top Tabs) allows direct access to Login pages of our online services, associated websites and public interactive tools.

Functional use of the various tools are not affected.

The cascading menu bar (Below Site Title) gives a better picture of content and access to your pages of choice.

To tidy up the discussion pages and avoid confusion, the Public and Research Discussion Forums are now combined.

You can also use Yahoo and Google to search this site and the world-wide web.
