Sure thing!

1. • The contest actually lasts 6 days. A theme is announced Tuesday and the latest to enter is Sunday at 11:59 new york time. That's the deadline. Winners are announced Monday.
2. • Yes, mobile phone photos are fine. It's not a photography contest.
3. • You don't have to put a link in the comments, but it helps if something happens and I'm late on judging the entries, or something. Makes them a lot easier to find and not be missed.
