Not sure what you mean by fang covers, but I think those that may appear "hidden" to you were probably just removed by the owner. These guys are right, search lift and you'll find more than you can possible imagine. I'll save you time though and point you to a really good one:

Feel free to keep asking questions, generally speaking we're more than happy to answer questions and discuss problems that we have before since that's how new solutions are discovered. Just try to search first, then if you need help ask and we'll either answer the question or point you to the right thread(s).

Welcome aboard!
