I joined up for the full membership a couple of weeks ago, and have been really pleased with the results. I've got heaps of cookbooks but I'm not using them for cooking out of, and they were taking up a lot of space. I've made recipes out of 3-4 books that I haven't used in years when I've put in a search ingredient. As it has gained popularity there have been a lot more cookbooks that have been added to the index, included TM. For $25 a year, its making my existing purchased books better value.
