All the entries are in and voting has begun, if you want to check it out.
If you haven't already seen the blog post: I have decided that I will keep doing DS Challenges as long as enough people enter in them. The next one will start in a week or two and last a couple months or so. Still deciding on the restriction and the prize. Will probably be worth about the same as the prize for the first DS Challenge.
As for the contests here in the forum, I'll leave #20 up until people show interest in it again, if they do. Those will still just be for fun.
