I'm kinda sad I cannot participate since I'm outside the US. Nevertheless, the other admins and I will certainly help to promote the contest in our site. We'll put it on the front page as soon as possible and we'd like to highlight the discussion post but don't know how to do it. If you can help us with that, it'll be annother way to promote the post. We've already made the announcement on our Discord server for people to see. Another way of getting exposure would be to ask our partners at Brickset to help you, as well. They habe a lot of viewers on their webste.
