Okay, we're rolling now. As of now, I have the ability to have any post submitted to that one particular category show up ONLY on the unique page assigned to it, and PERFECTLY in sync with the format on that page. (For reference purposes my "News" page is found at http://www.polhemus.cc/blog/news.php).
One of the most important things I've discoverd ("DUH!") is that you must have the .php extension on the file. I presume Apache (in my case) has to have this to know to invoke the PHP module. Others can fill us in on that far better than I can.
Also, I've hacked the "loop" portion of the code so that it shows only the title (with no permalink, since I just want to put my news items up and don't need the "comments" feature).
What I need to do now (further hacking required) is (1) have it show the posts only from the current month (but ALL those from the current month) on the "live" page but one the option of going back to prior months; (2) an option for "(1)" so that would allow me to have a list of links in the "sidebar" area showing titles of older articles--this option might work with having, say, ten "full" articles in the mainbar and all the others in the sidebar--maybe all the articles YTD.
Any recommendations along these lines would be very welcome.
