Sheri:
I'll pop in and answer part of your question -- the ECTA website is
www.ecta-lsr.com, and there's link to it on the homepage of landracing.com --- look on the left side of the page about midships down from the top. You'll be able to find records, runs, and stuff like that -- but not a rulebook.
Rules are, as you've seen posted here, pretty close to SCTA rules but with some significant differences in a few areas. If you've got a specific question about a rule -- go ahead and ask here. If you want the full set -- hey, that's how ECTA makes a buck -- you buy a rulebook! Just like the other orgainizations.
Best regards, and thanks for the photos.
