Simplifying sign ups

If there's one thing that really bugs me on the internet it's those annoying 'Captcha' verification things.

Sometimes those squiggly words are so hard to figure out I have to increase the font size a couple of times.

Unlike the lovely little verification device above.

It's from the CoLunching sign up page.

Pretty clever don't you think?

And so much easier than a couple of annoying squiggly words!
