I'm pretty sure all of the guides on the website are written and handled by Cher herself, while members are free to post topics about their own guides and stuff on the forums. You could begin by posting your mini guide here
and see how it fares there first.
Very rarely do threads and guides get stickied so don't count on or demand for it too much. If someone were to use the search feature they'd run into the thread eventually.
Not sure what you mean by "Link for downloading the guide".
