To whom it may concern:
I don't suppose there are many stipulations. The only criteria are that it must be about robots and that it must be submitted before Robot Day (July 10). There will be a judging panel, so mind your audience. There isn't a word limit, but something ridiculously long will turn away the judges. 5,000 words has been a previous limit, and it seems like a good limit to me. Also, the work must be original, but if it was written prior to the announcement, that's ok I think. Just be honest, or else you will get banned >.>
I'm pretty sure those are the only rules, but wait for further notice from the higher-ups. Also, MAKE SURE YOUR ENTRY IS 100% FINISHED AND REVISED!!! I cannot stress that strongly enough. If you turn in something rife with grammatical and spelling errors, the judges will instantly dismiss it. There are plenty of people to help proofread and edit/revise. Make sure that the process is reciprocal; if someone helps you with your entry, help them.
