As I have been reviewing the site, I have been renaming my sequence tags to the actual names for the sequences in question. I shall be moving the sequence links from a menu widget to a links widget. Which shall give me a different set of options regarding the positioning i.e. the order of such links.
In addition, while I have not yet found a way to reverse the order of sequence posts so that they may read from the top down, I have discovered that inserting links of the form:
will start the reader at the bottom, and therefore at the first entry in the sequence. This, at least, will allow the reader to scroll upward through the posts in date order–which, after all is the “normal” blogging order: oldest at the bottom, newest at the top. And perhaps, this is good enough.
