I vote for #2.  I like the reason for doing #1, but it is a Microsoft way
of solving problems.  @NICKSTOYS.COM is just as valid as @nickstoys.com,
while nearly the entire world might prefer @nickstoys.com, the other is
valid and so 'forcing' a user to use it seems, well wrong.  I would see no
problem making that the 'default' behavior as long as there was an
override.
