Hi
Can some one suggest on how we can change the format for user stories.
As I don't see the correct format for it under my project.
or if you can suggest how to add or delete issue types.
Thanks
You probably have the wrong "issue type screen scheme" selected for your project, or the scheme is not correct.
Your admins can change these - see https://confluence.atlassian.com/adminjiraserver071/project-screens-schemes-and-fields-802592517.html for a full explanation.
For issue types, have a read of https://confluence.atlassian.com/adminjiraserver071/defining-a-project-802592364.html#Definingaproject-issuetypesIssuetypes
