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.

If you replace them with uppercase letters from the start will cause issue's.

on the first replace to 'TTTT'
on the second replace to 'AAAA'
by keeping them lowercase you kind mark those that has already been replaced, then you just need to uppercase it to get it correct
Why not replace them with the uppercase letters by default?
