We have two tiers of content, premium and metered. This is a metered story.

If you're being asked to register, it's because the website has counted enough views in the past time period (I don't know how long) to ask you to subscribe.

If you're brand new/new browser and click on the story, you should get a "2 free articles left. Create Free Account" notice on the bottom left.

Right now the deal I see is $1 for three months, which is pretty decent.
