Either way is fine. As long as you don't have both topics open at once. Just PM me or another moderator. Or report the WIP topic and ask to close or move -- whichever you want.
Some members like to move the topic intact from WIP to the Made w/GM forum, so they can preserve the discussion. But in some cases, they want to start fresh with a new topic (and close the old one).
If you decide to close the old WIP topic, then I can leave a link to the new forum topic once it's opened. Up to you.
