Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Not a kata issue + I have no idea what the "red box" is.
The puzzle was fine, but seems that only one way of "rounding" is accepted. That's fine, I figured it out and learned a new Java method.
But...
The interface is not working for me. I could not see results. The "red box" was too small and scrolling was not working either via keyboard or mouse clicks or drags. I finally gave up and developed another way, then copied code to the window.
If it helps: I'm on a Windows 7 desktop, using Chrome to view site.
