Well that doesn't look terribly different to my PHP script so I'm not sure 
why a robot would find any difference between them...........?? (Mind you, 
I'm not as "up" on javascript - I've not gone that route due to more and 
more people blocking their browsers from accepting it).

The PHP script that constructs the email addresses is not in the same file 
as the one calling the function - it's called from within other scripts in 
other files that build the pages somewhat dynamically, so the robot would 
need to know how all the bits go together in order to make sense of it. I 
think!  :-)
