This is just an example game (taken with permission from the WordPress Chess Teaching blog) of another way to publish chess games with the LT-PGN viewer that probably also is working in Firefox.
I'll describe this method in more detail later, if needed.

Update April 2010
This chess publishing method stopped working and the content of this post has been replaced by some original screendumps.
