To whom it may concern:
I had a bounty out on this question. I accepted an answer before the bounty expired and awarded the 50 points. But then the bounty actually expired and I got a notice that the answer had been auto-selected and only the autoselect-25 points had been awarded.
I'm really darn sure I checked the check-mark as I said. I'm sure it's possible that I forgot, but due to the low volume of bounties on the site and its newness, I'll trust my memory for now.
