A Dead-Simple Change That Increased Our Conversion Rate by Over 250% (blog.kajabi.com)

I was all set to read this but then the article got covered up by some lightbox crap on which I couldn't find a close button (not that I tried very hard).

That's a very nice discovery from A|B Testing.

Trying to figure out more about Kajabi, I started watching your "getting started in 5 minutes video" and see that you e-mail your users their password. I feel pretty strongly that websites should never do this... I'm wondering what the rationale is?

N=?

It would be nice if we knew more about the test.

How it was conducted, sample size, length of test, etc.

Only thing I can tell from the post was that they changed the text of their button and that it was an A/B test. Pretty light on info.
