Ambiguous [Submit New Thread]

The [Submit New Thread] in the post editor is ambiguouis. It might mean

  • "Post this as a new thread.
  • “Leave here and start a new thread”

It is possible to get to this screen without a clear recollection of just what the situation is.
There is a bandaid fix for the case where user erroneously believs the second option – there is an error message.

The button would be clearer if labeled simply [ Submit ]. It is the superfluous words "New Thread’ that cause the confusion.
