Joe,
I don't know what is going on for you machine. I used the file you sent, and the following metadata plugboard:
Code:
epub:KOBOTOUCH = ([{authors:'re(re($, '(.*) & ', '\1 and '), ' & ', ', ')'}] -> authors)
When I sent this to my Glo, the author was shown as "Jessica Fletcher and Donald Bain". The line from the content.opf of the file on the Glo was:
Code:
<dc:creator opf:role="aut" opf:file-as="Fletcher, Jessica & Bain, Donald">Jessica Fletcher and Donald Bain</dc:creator>
Do you have any other plugboards? The one you show is for "any format" and the device "KOBOTOUCH". Do you have one for "epub" or "any device"? I am not sure of the precedence when the more generic device or format is also defined.
