Comment 4 for bug 333378

Thinking about the user story for this, I know that it would be easier for me to grok what had occurred if the email presented not just the before and after states but a summary of what had changed:

The moderators for the Paul Private community have changed:

Fred is no longer a moderator.
Wilma is no longer a moderator.
Barney is now a moderator.

Previous Moderators:
Fred
Linus
Lucy
Wilma

New Moderators:
Barney
Linus
Lucy

I will implement such if there is no objection.
