On another project that I work on that uses Jira anyone reporting an issue 
is asked to create an account and create the issue.  That person then 
becomes the "reporter" of the issue and it assumed that the reported would 
review the resolution of the issue as well.  Not that would happen on 
*this* project but occasionally an bug might be filed on a project, someone 
responsible for the component fails to duplicate the problem and just 
closes the issue and marks it as resolved.  Occasionally, a fix to a bug 
might be committed but doesn't actually fix the problem as originally 
reported. If the person that initially reports an issue is also responsible 
for confirming that has been resolved to their satisfaction it saves a lot 
of headaches.
