Does a fic have to be smutty or based around a pairing to be submitted for coldest hits?

No way, man!  

Seriously it can be whateveer you like, Sometimes the theme may specify a pairing but that doesn’t have to be a main pairing and can be left up to interpretation.  And i mean i guess it should be related to the theme, but tbh I don’t even know how solid a rule that is too!

name of the game is have fun, meet some new friends and writers and then if you want to you can go nuts in the promo wars.
