You get to guess the exact minute PaperBackSwap has its 1,000,000th actively posted book entered into the system. Only one guess! There will be prizes for first, second, and third places. You can select any minute of any day that is not already selected by another member between 2/27 and 3/12. No one will be able to add a guess once the counter hits 999,000 books. It's getting close! For details, go to www.paperbackswap.com. It's free (at least for the first year). There are many homeschool books and good children books available for swapping. Have fun swapping !
