Bingo Cards: This is a year long challenge, and anyone can join at anytime. Click
https://docs.google.com/forms/d/1jynpGESe_P25fTsSYx06e4FaxVj6JdHlPR2OTY6LvGc/viewform to sign up. I will send you your card. This works sort of like the bingo challenges of yesteryear- you have to produce a fanwork (or fanworks) with the indicated theme to earn a ‘Bingo’- diagonally, vertically or horizontally. You can use as many or as few fanworks as you want to fill the slots and you can use chapters of longer works if you like, and there’s no minimum or maximum word count. This challenge is open to any kind of fanwork creator, including writers, artists, gifmakers, vidmakers, podficcers, and even betas, so anyone can join!
Once you have a ‘BINGO’ (whatever you consider this to be… any line, full card, etc.) you are encouraged to post your work(s) in our challenge collection, listing in the notes which BINGO spaces you’ve filled. You may fill your card through doing one fanwork per space, one fanwork that covers three spaces, or one fanwork that does the whole card! Any combination is allowed- the point is to just EMBRACE THE RICKYL.
This challenge will expire at 11:59PM EST on December 31st, 2016! Let me know if you have any questions!
