Bodhi switched from Vanasco-Dowty to McDermott because Vanasco-Dowty was too
hard for people to use.  I remember playing with it and I think the issue
was that Vanasco-Dowty is much harder to figure out uppercase and lowercase
than McDermott.  Note that that's not something you realize by reading the
documentation -- that's only something you realize by having your captcha
rejected because you typed "CIKLOPSUVWXZ" instead of "ciklopsuvwxz".

I'd love to see someone create a new captcha algorithm that was easier to
use.  I'd work on it myself but I don't know what a computer can or cannot
read.
