personal communication citations

hello all,

when i insert a personal communication reference into a word
document,
it is formatted just like a regular reference.  Shouldn't it
be
formatted as a personal communication, which would vary with
the output
style?  Usually, they're something like (Smith, Personal
Communication).
But instead of that, I'm getting (Smith, 2008).  Any ideas? 
This seems
odd.

Thanks,
Allie
