Really?  Does this work?  I assumed robots were clever enough to ignore 
hidden fields, so I've never tried it.  What I've done with my email 
forms is to look for identical values in multiple fields, since the 
robots will often put the same value in each field.

Really?  I have a blind friend who helps me with accessibility 
testing... his screen reader (Jaws for Windows) ignores hidden fields. 
If there's a screen reader that reads hidden fields, I'd appreciate 
knowing about it!  Thanks!  --Ben
