they sort of make sense.  I don't think I've quite learned enough.  I'm 
currently fighting with trying to make my changes visible.  It seems 
like not everything is getting invoked in the right way at the right 
time.  hopefully it will make more sense in the later morning rather 
than at 1 a.m. (note: shortly after I wrote this message, I discovered 
hda1 on my mail server was toast)
