thanks for replying.

well......I really don't need to go that far. I think for now a random
text is enough.

Now I can make my webpage generates a random combination. All I need
next is to creat a text area to compare with the randon code
generated, as what I said in my first article.

Can anybody me with the rest part of the verifying process?
thanks.
