Where can you find previous results of a PYW event if you want to start one?
Go back to Games section and below all the threads you'll see a part called "Display Options". It's possible that your forum settings are such that under "From The" you have "Last Day" chosen. If that's the case you see only threads that've been active very recently. What you need to do is change "Last Day" to "Beginning" and click on "Show Threads" button next to it. Then you'll see all the threads that were ever opened in the Games section and you'll be able to track down past PYW champions.
