Accessability

I have cataracts and suffer from tinitus and your service denies me access to hundreds of websites. I cannot decipher your craptchas, I cant distinguish the letters squeezed up and I can only hear mush. You are discriminating against disabled people such as myself and denying business sites my patronage. I intend to take this matter further to the equal rights commission -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
