Hi Michelle. Interesting question. I think using a blog with tags (or categories) would be easiest for you to work with. But as far as the reader being able to read them in order...
A list of posts is generally sorted by date order - from newest to oldest. So if you copy the stories into blogposts in the right order, they should then sort in order as well. However, since it's newest to oldest order, the reader would have to read the posts from the bottom to the top. I suspect that's part of the problem.
Were you looking at Wordpress.com (hosted by them) or Wordpress.org (take software to your own site)? Com is limited in what you can do. If it was ok that they read from bottom up, you would be ok by copying the stories into posts in order. Even if you had to fit one in later (or you found you put some in the wrong order), you can change the date/time on them so they reorder.
If it's not ok to read from bottom up, I'm not sure there's any way you can do that in Wordpress.com. In the Wordpress.org site, there are several
ordering add-ins that you might be able to use. But I'm not sure if any of them could be used at Wordpress.com.
There's also this "
Write a Book" at Wordpress.com, which is interesting, but not sure it's what you are looking for.
At
Typepad.com you can tell it to reverse the date order. That might work for you, but Typepad is not free. It's not expensive, but it's not free - the basic plan is currently 4.95 a month. They do have a free trial, so you could test it out first.
Anyway, haven't tried any of that so don't know if it will actually work. And not quite sure I've understood your problem properly. Maybe it might trigger something for you though.
