We help the helpless (fanfic writer)

Possibly of interest (I've seen a few fandoms people have mentioned here in the nominated fandoms & not just mine I think!):

Sign-ups for the Kaleidoscope fanworks exchange are now open. Kaleidoscope is a "multimedia fanwork exchange for rare chromatic source fandoms":

For this current challenge, we are defining chromatic sources to be sources with chromatic characters or people and by chromatic creators. We use the term "chromatic" as an umbrella definition for "person of color", "non-white", "multiracial", "indigenous", "sourcelander", "hyphenate", "diasporian", etc.; while we acknowledge that it has shortcomings. Similarly, we accept that there is a certain flattening in our "white/Western/other" terminology.

Kaleidoscope is open to all sources with chromatic characters or people and by chromatic creators, from animations to books & literature to folklore & mythology to movies to music to real people to sequential art to theater to TV shows to video games and including anime/manga/manhua/manhwa, Bollywood, C-Pop/K-Pop/J-Pop, fantaserye/telefantasya, komiks, lakorns, Nollywood, telenovela, tokusatsu and wuxia to name a few commonly known and region-specific genre terms. We welcome artworks, graphics, stories, vids and potentially other types of fanworks in English, in non-English languages or in both, particularly in English dialects and non-English languages associated with chromatic cultures.

This is going to be amazing, so if any of your fandoms have been nominated I encourage you to check it out!
