Beat,

Automatic submissions to any CAPTCHA-protected site require configuring
robot for each particular site (or engine--phpbb or phpnuke). At least,
the image/field relation should be configured because robot should know
which image should be OCR-ed and to which field the result should be
pasted. And of course, some CAPTCHA could be OCR-ed because people make
money on this and there are a lot of programs for OCRing. I do not know
if your CAPTCHA can be deciphered because I've not worked with such
programs :-)

Sincerely,
Alexander
