I have tried to follow the JIRA online document to set up my project, users, permissions, groups, etc. but the instructions don't match with my JIRA menu. I think that even I'm an Administrator of my project, I do not have all the permissions to do everything described in the document.
Since the default permission settings are used by over 1000+ other project in DI2E, others must have found a work around this issue but I do not know how to search/view their answers.
