I think the result -- it's from several things Barry. As you know, we have been in this business for a long time, as you said. Right now the enthusiasm for independent reading and for books in schools, is at an all time high, somewhat comparable to the whole language period of the 1980s. Teachers are going back to books after some flirtation with digital, and trying to make that work. These are largely printbook sales, although there is an appetite for digital subscription programs. Our classroom magazines have been amazing in their growth over the past three or four years, because the non-fiction is so beautifully attuned to the common core, and at the same time, our digital companions make it possible for the teacher to, on one hand, take advantage of the simplicity of the print magazine program, which is beautifully orchestrated for their teaching, and also can tell their kids to go look at the digital supplements, and/or teach them themselves the digital supplements on their whiteboard. So that's boosted up to classroom magazine, but underlying all of this, I think there is a dissatisfaction to some extent with core printer basal textbooks. People are looking for different kinds of solutions, and they are customizing their own curriculums to a great degree, so we work with them on that, as well as providing a professional development and support services. So I think it's just a perfect storm of wonderful reception for our supplementary business, and its growing by leaps and bounds, and we are investing more heavily in it. In respect to the clubs going forward, I think we have achieved the remarkable increase in sales since January of 2014 through December of 2014, a one year turnaround program that produced 30% some increase in sales in clubs. Obviously, we are leveling off a little bit right now compared to the tremendous gains that we had last spring. But we see the clubs as part of this overall independent reading thrust, as gaining traction with more teacher sponsors and more child use as independent reading becomes more popular. So we continue to see growth in that business, but the one time growth that we had in the last year which has been so dramatic, we don't see that continuing at that level of sales. Does that answer the combined questions Barry? If not, I can also ask other members of the staff here to talk about those issues?
