HI all!

as I see on the sign-up web pages there's a word verification against automatic registration. I thought that there is an image database behind (jpeg format). And about the random (?) characters that appears on the jpgeg,it seems to be a random ASCII character generator. I also have noticed that the word verification contains letters and numbers only. Looking at ASCII table there are 3 intervals to "catch" numbers and letters.
Considering the facts above I think that coding such a word verification idea makes a web server ready for a lottery-machine.But where's the winning ticket??

PS
any comments,mores simple ideas?
thanks in advance!
