> Also FYI, your homepage has a 2015 copyright notice on it. No big deal, but thought you might like to know since it could put off particularly "nit picky" types of customer :)

If that's when the work was created, then that's correct. Copyright notices aren't there to tell you what year it is today. They are there to tell you when the work was created. If they change it to 2016 when the work was really created in 2015, then that's an invalid copyright notice and equivalent to no notice at all.
