Let's Build Content!

My purpose here is to create a huge list of links to every kind of free worksheet possible. Over the past several months we've added links to our electives pages and a few throughout our core subjects. I'm now wondering if there is some way this site could also provide a "favorites" so that visitors could bookmark things within the site that are worth coming back to. I'm not getting too many suggestions for links to add though, so help me out here if you have some noteworthy idea! I sure could use it! We've nearly doubled our traffic in the past year, so I know people are finding the site and using resources.
