First, a note about how winners were selected. First, we scanned the entries to delete any that didn't have the correct phrase. Then we deleted the multiple entries. No one was disqualified for multiple entries. (Although I would like to note to the three people who submitted entries more than fifty times each...please don't do that again. Also, please don't try to submit twenty or more entries with different names and the same email address.)
After the entries were cleaned up, we used random.org to come up with a completely random number, and picked the corresponding person from the spreadsheet of entries.
