Makes sense.  Maybe we should look into reorganizing the preferences a bit, so
all of these options make sense to the end user when put together.  I haven't
really messed with preferences except for tweaking prefs.php files.  Is there a
way to disable a pref when another pref puts it out of context?  Or would that
be pushing a custom pref form?
