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.

Great comments A+
from the description:
The output should be two capital letters with a dot separating them.I agree.EDIT: Oh they have done that now, but I suggest that the either sample tests should have lowercase letters like that, the description should mention it, or the lowercase letter thing shouldn't be in full tests

I kinda feel like if there's meant to be a full stop between the initials, there would be one at the end too. Not that it really affects the point of this kata, just an observation.
Recommend that the description include that the answer must be uppercase.
