  1. Hi Ian,

    I had the same issue with Snorre Vestil. I’ve submitted my design yesterday, but didn’t have any confirmation. I’ve resubmitted it again through the contact form (I thought that it was not received). I hope I can join the contest with my design



    1. Lynn was out yesterday, and I was traveling internationally, some replies have not been sent. We’re catching up today. We’ll post a complete roundup soon, if yours isn’t there please hit us up over the contact form and we’ll get stuff in order.
