So I am going through the rulebook as posted on the USCRA web site, and the files are dated as being updated last on Feb 25 2005. Then I go through the files as posted on the Groups page, where I have been telling folks to go to look at the new rule book. There are significant differences in what is written: (Specifically, the interpretation of nos. 9 and 12 in the first instance) Should the rulebook be changed or should the web page be updated?
I have posted this to the USCRA line . . .
