Totally unrelated. You could do angst for D and comedy for G and then dialogues for Y. Basically whoever signs up has to write 26 drabbles related to those words on whichever pairing/character they sign up for.
Hum sab words pehle hi de deinge. So everyone knows what they are expected to write on!
I could choose to do the challenge and write on B first and then T and then F. I'll just make a post saying I have accepted this challenge and will post all my drabbles here.
All we need to do is clarify the rules in a Masterpost and link up writer's threads as and when they sign up for the challenge and start posting!
