001. No one is going to research how rare your ship/fandom/etc is.
If you judge it to be rare, go ahead and request it!
Also, no ship/fandom/kink/etc shaming.
002. Non-rare ships/fandoms/etc can be included in fics as well, in any capacity and to any extent that you wish.
But the focus must be on the rare ship/fandom/etc.
003. You can prompt as many ideas as you like, and you can fill as many prompts as you like.
Likewise, prompts can be filled as many times as anybody wants to fill them.
004. Once you fill a prompt, please post a link in the ‘filled’ thread so it can be added to the masterlist.
