Tbh, I didn't know that a winner picker existed, I always used a random number generator between 1-number of participants, and the number that was chosen was the winner.

There should be some option in those thread like a poll to click on "I want to participate" and when a time runs out then a thread script will select a winner automatically and post a winner name there, something like that, I hope its possible to do it.
