It must be based off of your IP address - it must keep an entry in its database for the last message sent to each IP address.

You mentioned before about wanting to make an archive of a message - if you are interested it would probably be fairly easy for me to put together a little "screen scraping" script which you could run to grab the contents of any one particular forum post into a local .htm file on your hard disk.

That would be done using this address, which allows for displaying a single message:
http://moi3d.com/forum/display.php?webtag=MOI&msg=1382.1

Thanks! It's now pretty close to how I imagined it, kind of a hybrid between NNTP style (with the thread list column) and the regular web forum style.
