I have now uploaded a copy of this to the drafts folder. I am not very
pleased with it; there are several paragraphs where I am really not
sure if I have understood the author. I have commented all of these.
Perhaps Robert could have a look at the draft.
The whole chapter is based on the use of the Report Builder plug-in
which I do not have.
2 points:
1) While uploading the file, I saw the forms chapter (which Robert
says he couldn't find) in the same folder.
2) The site is behaving very sluggishly. In particular, when you
upload something, the upload screen does not clear, so you can't tell
if it worked.
