I chose letters that are fuzzy so they would be harder to decipher via optical character recognition, which is a real problem for CAPTCHA systems. Of course, the fuzzyness makes it a bit harder for people to read too, but I feel the tradeoff is worth it. Yes, this is a very good idea.

If the letters presented in a give CAPTCHA are REALLY too hard new rendering of the same letters is obtainable by refreshing the help page.

Hmm... but would users actually do that? Some letters are extremely hard to read... for example, the D in the font where it looks sorta like a harp... Is it possible to prevent certain letters from appearing in a given font? Klaus
