The one week doesn't bother me (especially if it's easier to track!), but I was wondering if we could have a few more of the challenges posted on the 1st. The first week has always been hard because there are fewer challenges to choose from, but I'm finding that it's hard to stretch the current number for 10 days. More challenges would be great, of course, but it could even be done without adding more for the month, just posting more of them on the 1st than on the 10th or 20th. I don't know if it affects anyone else's buying, but I know I can only get a certain number of new releases each month, and I'm less likely to buy them in a week when I've already done the challenges that interest me.
