As manually updating can be something I may not always get round to as quickly as I should, I am going to keep a web log of interesting developments I learn about. That's quite a bit easier to update! I shall also include an RSS feed on this page which means the headings will appear below and you can also add the feed to your own site or desktop. I wish one of the Machin specialists would do this - it would have saved me a lot of time! Anyway, I'll start this now and something should appear in a few days.
