Are you clicking on the links in the index post?
They were done when the URL was paste-and-cut.com.au
The URLs now are all paste-and-cut.com as the forum was not eligible for a .com.au.
I've not had the time to go back and update all the URLs in that index as it is a manual process, but you can edit the URL in the address bar in your browser to remove the ".au" and it will get you to the updated page.
