No, take a look at the last one:
- First, the discussion thread.
- Next, the theme voting.
- Next, the jam start / end thread.
- Then, the final vote thread.
- Optionally, a ‘winner game’ thread (not present on the last one).
The winner only organise the jam. If I’m not wrong, I can’t even participate (even though the users that will vote for the winner game, not me).
