Once you find the pick up games it's easy just click on the camp or tryout you wanna attend . Than pick your primary position , if it shows your name in green that means your comfirmed. If it shows in yellow don't panic it just means your unconfirmed but don't rule your self out . People tend to have things come up and a spot free's up . Other than that just be on the forums around those times if your not comfirmed .
