Thank you for bringing back this wonderful tool. It's truly unique, allowing us to train on methods only found in books. Also in keeping with the original sense of TGH to provide an enjoyable and motivating way for learning and getting better. I was much disappointed when I noticed it was no longer a problem set. I imagined that due to its unique features it was not easy to implement in new TGH engine. I was just on the verge of asking if there was anyway this problem set could be brought back, even if just a link using old engine and not offering any xp. But here it is . Wow. Again, very much appreciated. Best ec Dave
