Please implement a MERGE feature for JIRA, so that separate related tickets can be merged into one parent (ie: RT can do this).   This will help cut down on the noise level where an issue crops up and, for example, several users open tickets about the same issue.    As it stands now, I can "link" but that's just not useful for us, as I still must answer each individual ticket.   The Merge feature might also have an option to set the destination to where alerts go (which is usually the owner of the parent ticket, but flexibility can be useful).
