Someone should link the Jann stream where the opper withdrawal was discussed (JK then being the replacement wild card) and he said we should give opper a few weeks to reconsider and if he did change his mind no-one would object to a new spot being created for him. The chair is always open if he wants to come back. The "no-one would object" seemed obvious at the time. Now we have some objections but ironically none of the objections are that opper came back but the end result of having the extra candidate. But logically one implies the other.
