PSA: the poll on page is pretty decisive, with the votes being 11-4 in favor of the proposal. Please vote on page 15 if you haven't already.
If the result holds, from next season on, Rule 7 will look like this:
"7. A posted pick is NOT final. You can change the pick until the next pick is posted. If there's conflict, the changed pick has to change back to whatever it was before the next pick was posted. The honor system will be invoked here, but bear in mind that this is a privilege. If it is abused, we will go back to the way things were."
