OK, David, got what you meant. Now let’s see what can be done :-)

By using different URL:s you will be able to go through all of the messages with not much pain. For example this page:

http://www.ancientworlds.net/19373/boardthread/displayPage&from=150&step=50

is, according to my browser, the last page you can scroll to by using the “Previous 50” and “Next 50” links. Right?

From 150 “stepping” the next 50 messages we arrive to 200, right? So the next URL, to which the page (the URL of which is above) is NOT linked, will be this:

http://www.ancientworlds.net/19373/boardthread/displayPage&from=200&step=50

And after that comes this page:

http://www.ancientworlds.net/19373/boardthread/displayPage&from=250&step=50

After that I could not find any more messages.

This is not as easy as links, but I hope this helps?
