While I don't disagree that there are costs and cons to weigh when using a captcha. I find the Carnegie-Mellon one to be less annoying then most. They don't do *really* funky things with the words like toss the letters like salad or use horrid backgrounds. They actually use the creative idea of taking a fairly human readable word that has already failed computer recognition when it was scanned and OCR'ed from a digitalization project, currently the NY Times. And combines this with a word that has already been solved by humans. Thus you get a pair of fairly straight forward words that have always been simple for me to understand at least. That has not always been true with other, more homegrown captcha systems. Plus you get the community benefit of helping digitalize pre-computer printed works. I feel that offsets quite a bit of the cons of captcha's in general. As well as that Carnegie-Mellon has also included the ADA compliance portion. But, as always, your (general) millage may vary and only you (general) can make the decision on what is best for your (general) given project of the day. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
