What's so hard about it? You have multiple URLs showing similar content. You want the users to have access to the multiple URLs, but you want search engines only to index one of them. So you stick a tag on each page pointing the SE's to the official URL.

If we can get everyone participating who has questions to understand that simplistic explanation, maybe we can cut the questions from 50 to 10 or so? :)
