@Riot: League of Legends cosplays for PAX Prime

Hello Rioters, last year when I was at PAX Prime there were a bunch of cosplayers that every so often got up on the stage to display their costumes (typically in-between games).

Here's an picture I took last year: http://i.imgur.com/GopSUdV.jpg

To me it seemed like it was organized, like you couldn't just go up on the stage whenever you want. So my question to you is that do I need to do anything special or contact a certain Rioter while at PAX?

I'll be making Tundra Fizz and Fisherman Fizz cosplays; here's a photo of Fisherman Fizz wearing Fisherman Fizz's outfit. I'd show me wearing my Tundra Fizz costume, but it isn't quite done yet.
