Thank you for the info. I'd been hoping for an easy answer - the secret hideout is HERE - but it's good to know I wasn't a total failure for not being able to find it. What I'd been focused on when I posted is that I have no idea where to talk to Hockey RPF people...e.g. if I want Hockey RPF prompts for art or to find out if there are any Hockey RPF challenges. I only know where to find the end product - AO3. But it sounds like there isn't really any good place to find those things.

Also, I would be interested in some names to follow just as a starting point! Thank you for taking the time to explain what you know. :)
