number confirmation is actually a really good thing to put on any forum/members area. It prevents 'robots' from signing up millions of accounts thus bombing your server... It actually is pretty easy to make one in PHP, just get a background image and a font, load in the bg image and write some numbers / letters onto it. of course the php script calling it would need to know what the code is, to validate it.

Another metod is to post the date of a random location in the world, every times is a different time, it's nice
