End-of-Year Errata

Thanks to those who pointed out the mysterious, unsightly PHP errors that suddenly started appearing all over Subtraction.com this week. I went back through and fixed all the code (I think) so everything should be more or less back to normal. While doing so, I was reminded of all the fixes and tweaks that I’ve been meaning to find the time to implement… well, December has been a pretty poor month for posting frequency, to say nothing of under-the-hood changes, and January looks like it will be fairly hectic as well… but never say never. Happy new year!
