The document describes a Story Splitting Dojo, which is a workshop format for practicing the technique of splitting large user stories or epics into smaller stories. The dojo involves participants being divided into groups, each with a product owner, to work on splitting stories. The facilitator oversees the process without influencing the story splitting. Participants provide feedback on their experience in splitting stories and improving the dojo format.

Given a user of MyCoolBlog.com with its user name and wrong password When the user logs in Then the login is rejected And the forgotten password page is displayed.
