Cindy -
If you go to the very first page of this thread you will find a huge help thanks to Nancy. At the end of my first post and schedule she has added the post number for the beginning of each week. My instructions to A2 actually was made the day before the week started - on post #684 and the week 'officially began' with post #689 - but this is close enough - unless Nancy can go ahead and change it to the number for the instructions since this had to do with that week. Whichever way it is listed, this will give you a pretty good indication of the post number to go to for the blocks for a specific week.
Thanks again Nancy for doing this - makes going back so much easier!!
