im all for a captcha on the master server right now. the basic math idea
might work though...could probably make it more complexed as time goes,
randomize it a little. have maybe a few calculations in 1 go. but then again
with most scripting languages it probably still wouldnt be hard to crack if
you parsed number words as numeric with str_replace or something :) captcha
on the master server is probably about as good as it gets for now...

A simple grammar will generate the correct answer. I think we can try it, but I bet it is cracked in one week or even less :) I'm currently busy studying, but I can develop something until the end of the week (unless someone wants to send a patch :) Nuno4. QI test, with a simple math calculus (maybe in a phrasal form "what is the result of three plus for?")
