I need to delete a user account to make room for a new employee; I've deleted or unassociated all other content (issue reporter, issue assignee, component owner, project lead, etc) from the account in question, but Jira indicates that there are lots of issue comments associated with this old account. I don't see a way to search issues based on comment author, so I need your help. How can I get a list of all issues where this person left comments? I can't delete his account until these comments are wiped. Thanks!
