I decided to make a quick bug fix that would show an error in some occasions. My recent activity script practice really connected the dots to quite a few things I just was not totally grasping. This error would happen if somehow you tried to view a post id that did not exist, I have known about the error for awhile but didn't think it mattered much. Now it just sends you back to the main posts list page.
I also have an idea how to do my pagenation on my own from that practice too, basically it taught me more about manipulating data better. So yeah will continue using this setup and enhance, need that pagenation and then images.
