Decent (I use the term loosely because i am no fan either) Captcha systems also provide options for Audio to assist the Visually impaired. I am not sure how well it works but can only assume it is an improvement. One system I have seen removes the need fro captcha completly Instead it relies on Javascript & AJAX a short time after loading the page it it requests a unique serial number from the server using which is added to the form as a hidden field. if this field & SN is missing from the response then the request is rejected as coming from a Bot. since most bots do not (as far as I know) include a Javascript interpreter this process removes any additional burden from the end user. unfortunately at present in the battle between service providers & scumm* the disabled population is an unfortunate victim. I can't think of another slightly polite word for people who spam or hack websites. -- Zeus gave Leda the bird. -- https://mail.python.org/mailman/listinfo/python-list
