So did I get any of the things done that I said I was going to try to get done yesterday? Unsurprisingly, not all of them, but perhaps surprisingly, some of them, yes. I finally got a custom 404 page up, though it's very simple and boring right now and I'll make it into something more interesting later. I put in a check so the site doesn't try to show you a comic for a date after the current date or before the comic's start—right now it just redirects to the 404 page when that happens, but later I'll replace that with some (putatively) amusing messages about trying to peer into the future or go to the before times, or something. As for the Cast page... I was thinking of trying to implement that, but honestly right now there are only a few months' worth of strips, so a Cast page is probably unnecessary; it's not like there are old characters from years ago that readers may have forgotten. So for now I've just removed the link to the Cast page, rather than have a link that doesn't go anywhere. I'll reinstate the link when there are enough strips that a Cast page makes sense.
There's still a lot more I want to do with the site, but at least things are sort of getting done...
