Catchy app name!

Some suggestions:

- The "Start Building Stuff" menu is too wide (1/3 of the page width). When a user selects to build a contact form or a slideshow, you could hide this menu or offer a smaller menu instead.

- I signed in but still get the "Join Today" button on the home page.

- The button on the top right that reads "Free Account, Click Here for Dashboard" could be redone for a logged in user. Maybe "Welcome firstName! Start Here". Would your typical user understand what a "dashboard" is?

- Finally, a comment you'll probably hear a lot: let a user start building without having to join. As a final step, you could ask the user to join.
