We've had a question sent in by an IDZ member who is 13 years old. Per Intel policy our customer support team is not able to contact minors, so I'm throwing this out there in hopes that you see this reply.
You can and should submit to Level Up! Per the contest rules (https://software.intel.com/en-us/articles/level-up-2015-terms-and-conditions)
You must speak, read and understand English and you must be aged 18 years or over or you must obtain the consent of your parents or legal guardian before you participate in the contest. If you apply to register for the contest, if you contribute to the contest once you are registered or if you accept any contest prizes, you accept these rules.
So if you are not yet 18 years old and have the support of your parents, please submit. We'll need to do a little extra paperwork, and any potential prize money would likely need to go to your parents but you it is not a problem for you to participate. I'm looking forward to your submission.
