All of the scripts are available on this very site. Go to the boards front page (where you can see all the forums). At the top, just above the "Fanfic" section of forums, is a link that says;
Lois & Clark Scripts now available in TXT format!
http://www.lcficmbs.com/scripts Click it (here or there), and there'll be a list of all the eps. Clicking the ep title will take you to the tv.com page about the ep itself. Clicking the "Text" link next to the ep title will get you a copy of the script. BGDF is unusual in that it's in JPG format. Rather than written-out text, it's a series of pictures of an actual production script.
