Both points also apply to the audio captcha, as you have to a) understand the word and b) from this infer the correct writing. Which becomes even more difficult as English is a language, where the spelling/pronounciation-relation is quite loose (plus you have British/American spelling varieties). - - René -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkvAwsoACgkQ4UOg/zhYFuDM+wCbB+vkP+PnoTU8jnJv89Q2MdGk 46gAn1bsovc1aPbwWzP9A2g+iSGIf65r =SoEU -----END PGP SIGNATURE-----
