Well, it depends on what kinds of tips. Are you looking for general camera, composition, and exposure guidelines? Park-specific guidance? Scene-specific? The only detailed threads I'm aware of usually deal with fireworks shooting. There's not a lot of "go to this exact spot, and shoot this way" kind of thing.
It might be easier to just review the thread list in the forum and grab potentially relevant titles.
if you're looking to develop you ability to "see", especially related to composition, you'll find better help off the site. Several members have published info in blogs and such like I think you may be looking for.
