Hi davidfor,
Thank you for the time taken to reply.
I figured it out eventually (sinking head in shame) - I simply had to add the string "author" in the driver setting (where in the example "series" was used), and it actually works.
I tried with a small number of books and they were all neatly stored under their respective author on the Kobo.
As a suggestion, it would actually help get a better understanding if the thread
Quick Guide to Shelf Management with calibre 0.9.1 & above actually mentions (for those like me) that there are different tag/sorting options besides the default "series" used in the example, because that is where I hit the wall. But that is me!
Going to read some books now!!
