I have, indeed, completed all the “<— previous — view — next —>” links. I have been working on it a little at a time. And now I am done! Sometimes I would add the links from the older toward the newer. Sometimes, since I have been adding the links to all the new posts, I have added some at the front, slowly working my way from the newer to the older. Occasionally, I have done some editing on a sonnet or introduction somewhere in between, and have added the links while I was there, which made the process seem faster–like being dealt a wild card, or a free square in a crossword, or in “Scrabble.”
Now I can go back to archiving the site posts in skydrive, which had been my “do it when I have free time” project, prior to this.
UPDATE: I have undone it! No more extending functionality unless it can be done within what is available. Otherwise such things are far too difficult to maintain.
