Sorry for bumping this, but since it's ending on a Saturday, I feel like I have to.
The first ends around 7:55pm US Eastern Time tomorrow. The second ends 15 minutes later. And for those of you who prefer books made of bytes, both of these are available online and indexed here: http://fer3.com/arc/navbooks2.html.
