I'd be interested to know of any such plugin too. I have a number of 
images with directional camera shake that Refocus fails to handle at all 
well.

I looked under Select...but didn't see that, but then I was looking for it under the old
name...distress, rather than distort.  Thanks!

Me too :-) except Michael has already covered it so well.
The only thing I'll add is that when I first started, I was
worried about one of Apress' guidelines that said they wanted
a particular dpi, so I started out being careful to set the
dpi after taking screenshots. I was also sending high-resolution
versions of non-screenshot images.

Once we got rolling, it turned out that their layout people scaled
each image to an appropriate size on the page, and nobody really
cared what dpi the images claimed to have. As long as I took normal
GIMP screenshots of reasonably-sized windows, everybody was happy.

The Apress style guide also had warnings about not using Windows
Print Screen, and more warnings about various other programs to
avoid under Windows (mostly color depth issues, I believe).  None
of that was a problem with the GIMP screenshots, which worked fine.

Where can you get a copy of this Apress style guide?  I searched their site but was unable to see
this guide.
