writethisfanfic | Prompts! Lots of prompts!

There's been some discussion in this comm before about low entry-barrier challenges or opportunities to write fic; sometimes it just feels less intimidating to dash off a brief comment fic & it can be a good way to get some writing in even when you're feeling blocked!

I've seen a couple of holiday fannish things that might be useful for this. One is

insmallpackages, where people leave up to 5 wishes that anyone can grant. Wishes include prompts for ficlets & drabbles. It's too late to leave wishes, but perhaps some of the prompts might entice you to grant some?

Along the same lines:

fandom_stocking (still open!).

In both cases, it is asked that if you sign up to receive something, you try to do something for someone else, too. But it seems much less pressured & more casual to me than formal exchanges.

Not holiday-related:

fic_promptly, for comment fic. I've mentioned this here before but thought it was worth bringing up again.

Are there other, similar projects worth mentioning?
