If I know the code word, I always post it here and in the comments of the posted sweepstakes. Most members are good about posting answers and or codes if they know them. They say the code word of the day on Radio Disney at least once per hour but not during the preschool music from 12:00 noon to 1:00 p.m. weekdays or during the top 30 countdown on Saturdays.
If an answer or code word for any sweepstakes isn't posted, it more than likely means that no one knows it or got a chance to find out what it is.
You can always try guessing it also, which I usually try first. They are always a word relating to any of the contests they have running at the time.
