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.
Bad kata because conditions are specified unclear, and 'domain' term is specified incorrectly.
And actually there are no valid solution without using a big database of public suffix list.
Are somebody can say before googling, if alt.za, of.by, and pvt.ge are regular domains, or subdomains of alt.za, of.by, and pvt.ge are sold to an unlimited number of people by the registrars? In this, and thousands of similar cases, should we detect "alt" as domain or no?
