- Leave the new question open: answers to two essentially identical questions are split between them, or answers to the older one are reposted.
- Close the new question: no-one can post answers to either, because the previous question was already closed.
I think that the best solution is to edit the older question and reopen it. Does anyone object to me removing the last paragraph:
I will pick the winner as a combination of shortest code, usability, speed, and prettiness. I don't really care too much about prettiness, but usability is pretty important. Just make sure that you keep the code short. Good luck!
and then voting to reopen?
