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.
I really don't know what to return. have never worked with "IEnumerable" or pretty much anything like it.
I was using an ArrayList to save the categories and if i try to return it i get an error "Cannot implicitly convert type 'System.Collections.ArrayList' to 'System.Collections.Generic.IEnumerable'"
