Guidelines for prompting fanartists would really come in handy. A lot of us have good ideas of what kind of plots we want to see, but when it comes to art, our fandom might be so small/rare that -any- fanart is better than nothing. It would be nice/useful to raise awareness of artists wanting visual prompts, since art often seems tacked on as an afterthought, especially by people who aren't used to making/receiving much art, and therefore may not be inclined to ponder the logistics.
