Irish Gal,
All you can do is KEEP on reporting her...whether it be one time or a thousand times. I know powersellers can get away with MUCH more than the average seller because they line ebays pockets, but since you are also one yourself this fact can work in YOUR favor as well. Keep reporting her until they do something.
> And BTW--feel free to neg your NPBs, that policy doesn't go into effect til May.
