To answer Tycat, unless it's fists deal piercing damage, then no.
To answer Mereyn, I -believe- it was toward my characters '3 o'clock', but the bonus is added to your attack roll, which is displayed in the combat log (See the highlighted bit in the text box), thus it's non-flanking AB would be a 5. What you suggest is that all flanking rolls on the server would consistently be 2 higher than the combat log says it is. Which would be very bad.
But if you hypothetically add an unlisted bonus, it'd still only be an 18, while my AC was 19.
