Here is a recent bugmail for a rule engine change (July 2016):

    https://bugzilla.redhat.com/show_bug.cgi?id=1358619
    
    Red Hat Bugzilla Rules Engine <rule-engine> changed:
    
               What    |Removed                     |Added
    ----------------------------------------------------------------------------
                  Flags|                            |Beaker-backlog?
       Rule Engine Rule|                            |52


and here is an older one for the same rule (July 2015):

    https://bugzilla.redhat.com/show_bug.cgi?id=1246485
    
    Red Hat Bugzilla Rules Engine <rule-engine> changed:
    
               What    |Removed                     |Added
    ----------------------------------------------------------------------------
                  Flags|                            |Beaker-backlog?
       Rule Engine Rule|                            |beaker_request

It used to show the rule name, now it just shows the rule ID. The problem is, Owen tells me that the rule engine admin interface only shows rules by name, not their ID, so when I requested a change to rule 52 he wasn't sure which one that was.

It seems like the bugmails should show the rule name since that's more helpful. If it's not possible for some reason, then maybe instead the rule admin interface should be expanded to show the IDs.
