Under Discussions, the "Create New Topic" button appears after the title, contents, and preview of the new post.
As a result, "Create New Topic" tends to get lost, except for very short posts.
You actually start typing to create a new topic, and clicking "Create New Topic" is what completes the process.
Visually, "Create New Topic" doesn't seem connected to the new post. It seems like it belongs with the list of existing topics. So it seems like it's inviting you to create another new topic, not complete the topic you just created.
For me, it seems like there should be a "New Topic" button, which would open a new, clean page. The new page would have "Save" and "Cancel" buttons, which might even appear above and below the content.
