Welcome to the forums.
Sorry, but you're a little late to the game to provide input to the FAA regarding the Part 107 rules. That NPRM comment period closed almost a year ago (04/24/2015).
You can read it here: https://www.federalregister.gov/articles/2015/02/23/2015-03544/operation-and-certification-of-small-unmanned-aircraft-systems?utm_campaign=subscription+mailing+list&utm_medium=email&utm_source=federalregister.gov
For what it's worth, there were 4,640 comments received by the FAA.
I just put a new article in my blog about what we can look forward to under Part 107:https://dronemann.wordpress.com/2016/03/18/the-other-shoe/
There will be another NPRM shortly that basically exempts micro-class sUAS from the Part 107 rules and you will be able to comment on that for a short period. I will post an announcement here when the comment period opens.
