A few people asked me to create a writing post - to talk about fic ideas (whether they're inspired by kinkmeme prompts or not), brainstorm, post snippets and get feedback or just some moral support while you're working. Since nobody was really using the discussion post anyway, I have now changed it into a discussion/writing post you can use for just that: http://dceu-kinkmeme.dreamwidth.org/1668.html
Of course you can also still use it to discuss canon.

For the record, this changes nothing about the prompt post itself. You can still comment on prompts here, discuss prompts and post WIPs. The writing post is just there as an additional option.
