Hi Guys
I'm nearing the completion of migrating our existing website to a CMS and I've just finished creating all the various contact forms. The CMS I'm using has CAPTCHA built into it's form builder, which is great, but the only method available is the "decipher-the-noisy-image" method.
This approach works well, but it limits access for people who might have reading or sight disabilities. I've worked around this by having a "help" page which allows those with disabilities to contact us by telephone and I'm considering having a single-field form which says "Send us your email address and we'll contact you". Accessibility is of particular importance to me as a web developer, but from an organisational perspective; so is reducing the amount of form spam we receive.
So what I'd like to know is, has anyone in the community had any experience with other CAPTCHA methods and how have you managed to make them accessible to people with disabilities?
