Thanks for that Adman.
The site has no email address, so I've printed off the info and will put it in the post to them asking for a detailed explanation. And hope they give a thorough reply to my questions. I'll keep you informed. I have some knowledge of how the higher echelons of the mlís work as my uncle was a high-ranking member, and some of the things Iíd overheard as a child were unbelievable at the time.
