Just submitted one of my sites on botw. When you do this, they give you a promo trying to get you to include other sites. Anyhow, since I'm not submitting more than one I thought I'd share the promo code (only good for 60 minutes)

Enter the following code on step 2 of the submission process: c1yh18

Feel free to share it with a friend, but remember, it's only valid for the next 60 minutes.
