Home page

This is the introductory page for the website. 

The header bar at the top of the page takes you to the main features of the website, including the membership area where you can change your personal details.

The most recent updates are displayed on this page with links to other important parts of the manual. With more than 300 significant updates each year (and hundreds of minor updates), the online version is dynamic and up to date.


The page also displays the formula and image of the day as well as subscriber comments.
