The standard format for magic items (which is pre-formatted for you in the Round 1 rules document) includes a line for the wondrous item's name.
That means when you copy & paste the standard format for the magic item into the submission window, you should include the line with the item's name. The name goes in the Wondrous Item Name field (which becomes the Subject line of the message board post), and it goes (with the formatting) in the Description field.
We're not going to ding anyone on this right now, and Ross is going to put a clarification on the submission page. But... read the rules. Follow the given format.
I understand you may be doing that because you see the Wondrous Item Name field and don't want to double it up in your post. It's okay, it'll look fine. Maybe you're worried the item's name will count double for the word count. It's okay, it won't. Just trust us. Copy and paste that entire stat block into the Description field for your item, and type its name in the Wondrous Item Name field, too.
Thanks!
