Re: spam protection boxes

I actually just got back from the PHPCon convention in Milbrae (South San Francisco), Ca. I honestly forget who suggested the idea, it may have been Rasmus himself (my short term memory is shot), but the idea mentioned was to have some random text pushed into a GD call to automatically generate the image. Obviously then, if you supply the data to GD, you can verify the input as well. Voila! -Dash Weiler's Law: Nothing is impossible for the man who doesn't have to do it himself.
