Hi - I'm Jim Dobbs and that is me in the banner at the top of the page.
This site is my teaching 'portal' and links to other sites on the main topics listed below and then some more...

Most pages have links to external sites of interest that provide a service, have tutorials, provide dowloads or are just a good place to go to learn more about the subject...

The site is divided into the three main topics below and clicking the links below is a good place to start. For any other specific topic, go to the site map where everything is listed in alphabetical order.
