1. guide other users to good content.
2. thank an author (a little thanks goes a long way).
3. add links to other related internet resources.
4. endorse a calculation method to reassure other users.
5. inform other users about any errors you may have spotted.
6. inform an author about errors (they can correct and re-issue their calculation).

Get the most out of the forum:
All repository downloads have a link to an individual topic in the site forum. From the forum you can:

1. Subscribe to a topic so when the calculation is updated or corrected a post will be made and subscribers are automatically emailed.
2. You can also select a topic as a favourite to find things easily.
3. Review and edit subscription and favourite topics by selecting 'My Profile' at the top of any forum page (note: its the top 'My Profile' that takes you to your Forum settings - not the 'My Profile' beneath which takes you to your general site settings).
