Back of the Envelope

I'm something of a stickler for navigation, so I've implemented a scheme that makes it easier to find a series of posts. If a post is a continuation or clarification of an earlier post, I will start it off with a line marked Old Post where I link to the previous post. If there's a new post that continues or clarifies an earlier post, I'll edit the original to add the line New Post at the end, along with a pointer to the newer post. I had already been doing the latter, and I've edited my archives to implement the former. For the most part, this meant just adding a new line at the beginning, and I mentioned in an update if I had to re-word the post in order for it to make sense.
