when you are on the page where all the current challenges are listed, on the right side of your screen is a box that says three things (I think the first is create a challenge) but the 2nd is Upcoming Challenges, and the 3rd is Completed Challenges. If you click on the "Upcoming challenges" you can see all the challenges that are scheduled and when they start. but in answer to your question, if you are referring the the Alphabet Theme challenge, the letter E starts, I think, on Sept. 15th...but check out that upcoming challenge tab so you can see what is coming around the corner and can be working on your scraps before the challenge starts...Dawn
