There may have been some inadvertant miscommunication concerning the Poll deadlines. I believe you had mentioned, Duke, that you were going to open the polls Wednesday and leave them open until Friday evening.
However, when you opened the polls Wednesday afternoon, I'm assuming you tagged them for 48 hours, and vBulletin takes that literally, so that the deadline was exactly 48 hours after you opened them.
If one didn't check the poll threads carefully, they may have missed the actual deadline time posted at the top of the polls. It's only because I started submitting GTX votes Thursday evening that I noticed it, myself. I also assumed that the other managers would have noticed it.
Perhaps Spark @ GTC assumed the deadline was later on Friday, and didn't check the open polls until he went to submit votes at 3 PM, only to find the polls closed. He then PM'd the votes to you.
I'd say if you have those votes in hand, they should be accepted. I believe they acted in good faith, but were caught by the restrictive deadline option of vBulletin.
For any other team that has not voted, and did not PM the votes to you, then it should be too late, and they should not benefit from reopening the polls.
