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.

Because you're doing something wrong. Not an issue.
Why is the charAt method not working for Strings. In the following I am trying to call newString.charAt(cout) but it throws an unexpected type error when I do. It says that I need a variable, but it found a value. Why is this so? I have used this before in other programs on other IDE's and never experienced any kind of problems.
