Perhaps an alert in-game that could be ticked in options to allow a pop-up(Similar to CW announcements) notifying the player of Collectables on the site. Doesn't even have to say how many you have, just a green box to let you know you have items to collect or choose from.
Green digits next to "Match Score", post game, indicating points earned.
Thanks,
