Two motivators that I've noticed be a lot of help in smaller communities like this are collaborative projects, and rewards.
Broad strokes, collaborative projects can be things like:
- Having a community contest to write a bunch of short stories under a collective theme, to be compiled into a PDF for everyone to read afterwards.
- Organising a relay novel; each person writes a chapter at a time (with certain word limits), before passing it off to the next person, ending up with a full linear book at the end of it. Although this can run into issues if people end up writing slowly, having life issues, dropping out with no warning, etc.
- Have one user write the start of a story, and then invite members of the community to write the rest of it. As with above, these can be compiled into a larger tome afterwards.
Broad strokes, rewards could be granted for taking actions like:
- Winning a writing competition hosted in the community.
- Hitting a certain milestone of writing in their own worlds on their own time (say, after the first 50k words they've written in one world).
- Helping with the quality of the site.
And these rewards could be things like:
- Receiving fanart, either commissioned or drawn by a member of the community.
- Having a page of theirs highlighted, either in the Discord or on the front page itself (maybe in the gallery?).
- Have a profile for one of their OCs researched and made by a member of the community.
Finally, a rule suggestion I'm leaving to the end since I'm not sure if it's already a thing. There's a lot more to the profiles than the vsbw-like main sections, so don't make those mandatory if the rest of the page is high-quality. Currently, the front page presents the wiki as one for versus debating with original characters or characters from fanfiction; this could be reframed to being about discussion and analysis of original characters, often with a versus debating sort of angle. The
Getting Started on FC/OC page focuses on making pages in line with the standard format, including every relevant statistic and the like. If you want to more lean into the amateur writing angle, you could make almost all of this optional, if it in general meets certain standards of quality.
I may not want to make a profile for my own characters, but I'd be down to write some short stories for an FC/OC community event. I think that could be a valid part of the community.
