Here's the Wagn.org home page. Naturally, this site is built with the Wagn software. You can see several "cards" on the page with green headers. Everything in Wagn is organized into cards.

Double-clicking on the image gives you this interface to edit the image card. The same applies to most content on a Wagn website.
Clicking on the Edit tab lets you edit many parts of the card at once, as part of a form.
Wagn let's you make custom related tabs. This user tab shows information about Ethan's use of Wagn. Notice all the different ways cards can be displayed (open, closed, content-only, links, changes, etc). The "Tickets" are another type of card we created on Wagn.org using Wagn to help manage our software development process.
It's easy to customize the look and feel of Wagn. This skin is the default for all new Wagns — here's the home page you see when you start up a new Wagn:
