Thanks for moving this - didn't realize there was a discussion thread.
Now that it has come to light that a candidate was overlooked for this election, you should really lock this thread (or delete it), begin a proper nomination thread for potential candidates with a cut-off date a few weeks into the future so that everyone has an equitable opportunity to be acknowledged.
So we should wait a few weeks for a potential next (active) global moderator to respond to a PM?
Sure. I don't believe the situation is so dire that we can't take the time to do it properly.
I realize that this election isn't formal but that should not be an excuse to perform it in a half-assed manner.
No. The mistake happened and HostFat noticed it himself. That said, he also agreed that adding him now with the option of changing your vote is better than the alternative (which would be to start all over again).
This remedy still requires all who already voted to notice there was a change and I doubt people are going to keep checking the thread when it bumps since that happens every time there is a vote.
