I am that Series 3 has to be filled up before we start Series 4, but this is super vague. What if Series 3 is completely full, but some of that articles are about to be deleted? How will we know exactly when Series 4 is open? Will the site notify us when?
You know the huge banner that says:
SERIES IV IS NOT YET OPEN FOR NEW ENTRIES. FILL UP SERIES III FIRST. CONTEST WINNERS MAY MOVE TO THEIR SPOTS AFTER THE WINNER IS DECLARED.
That won't be there anymore.
