New Blog Templates: how to use new feature (showcase)?

Hi,

The brand new version of the (great) New Blog Templates provides a (great) new feature: user can select his template via a showcase inside a page.

The problem is I don’t understand how to use it. I activated this new option and selected a new page for displaying the showcase. But now, if a user sign to my site, he’s never asked to choose a template.

Please advise :slight_smile:

Best Regards
