I've tried as this page suggested, with the adding news entry link, and it has worked.
However, I'm still having some trouble with the $LAST_NEWS$ code. I understand that it is to post the latest entry that people right. What I want though, is certain entries being seen in only certain pages. If I delete the $LAST_NEWS$ code off the homepage and paste it into my created page, the entries do go there. But I would like, for example, that if I posted an entry on a created page, it will show up there and the main page. If I go to another created page and similarly post another entry, I would want for it to show up on that page only and the homepage. In my experimenting with this, it seems that any page with $LAST_NEWS$ code will receive any newly posted entries.
To put it simply, the way I would like it to work is: A post on any page will remain on that page ONLY and the homepage.
Is there any way to work around this and get it to show the way that I would prefer it to be? If I've missed a thread with how to do this, I apologize, but I did try looking. Any help is appreciated. Thank you.
