Damon Carr has again been working on the DAAB.  He's run FxCop on it (something I've been meaning to do, but just never got around to it).  He's put the errors on his site.  It's quite a list. unfortunately.  I still want to get the full 3.1 release pretty soon, so most of the fixes for these might get pushed to 3.2.  I'll see what others think about that.
