Send these questions to the support list people. I am not going to bring this up many more times.
Burning manager cards doesn't have to do with the Dunhill code -- manager cards predate Dunhill.
There is no plan to add this to GEMS, but we will add the functionality to the Poll Book some time after Nov 4. We don't want to confuse things with more TS releases this close to the elections. This functionality will be provided through a third card -- a administrator card, that has the ability to burn other admin cards as well as manager cards. The idea being, this will not be allowed for polling place people. Clearing results and deleting elections will also only be allowed with this card type.
