Of course you can still join. This week is catch up week.
From what wyldwytch has set up, there are 2 blocks per week, one easy and one challenging. You can do as many or as few as you like. I opted to 2 quilts, one of the easy blocks and one of the challenging blocks. Here is a review of the blocks to date :
