have to agree, I have yet to find a CAPTCHAS that I have not had trouble 
with.   and the "accessible" workarounds that some "Claim" to be compliant 
are either so clunky or so complex as to be worthless..

more than one site I have used and as soon as I run accross the Captchas I 
just close the site and go somewhere else.   I understand the purpose of 
these things and apparently they are actually being used to help 
transcribe documents but they are far more trouble than they are worth.

just my two pence
Bob
