Jane,
Great thoughts. Let me respond to them:
1. I intentionally did not set a deadline because, first of all, I know how difficult the writing process is and sometimes I find myself turned into a vegetable under pressure of a deadline. Second, I know students can get really busy with school, FIRST, and study for SATs and other standardized testing. So, I would rather they made submissions through out the year. Interesting thing to work on during the summer or on vacation

.
2. I already have someone telling me he is going to write on all three topics. I originally though it might help students by making them focus on one topic only, but then again, why not all three. But I ask you to submit only once for each topic.
3. With enough interests, and enough submissions, I would love to show the writing to everyone in the FIRST community, with the permission of the author of course.
4. I naturally assumed adults are going to be busy, but with enough interest, I would love to receive submissions from them (#3 should be interesting to the adults). There is no judging process in the moment, since I am still seeing how much interests there are, but if we get that far, the adults' submission will be judged seperately.
