Ella,

Making CAPTCHAS more accessible is very difficult as there will almost
always be someone who cannot complete it. There are some Œbetter'
implementations of CAPTCHA available but none that are perfect.Check out
the second link for some details. Unless a site has a serious bot/attack
threat, its usually best to use a non-CAPTCHA alternative.
