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.
Get started now by creating a new collection.
At least in F#, this is terrible. The instructions imply that making lower case characters in a string uppercase (and otherwise leaving the string untouched) is the goal (although it leaves this up to interpretation), but the "attempt" tests appear to expect non-letter characters to be removed and don't seem to work properly.
