A result of SquidgeWorld's previous life as Peja's WWOMB is that "combination" fandoms exist in the archive. In The WWOMB you could choose a single fandom called "NCIS/The West Wing" instead of choosing both fandoms, and that was fine at the time.
But because of the new archive, these old multi-fandoms mean a person wanting to read an NCIS story would miss ones using the NCIS/The West Wing fandom. So, I've undertaken a project to get rid of these, even in older stories. So there are some combination fandom fics that are15 years old, but they'll be updated by me, breaking them from the single combination fandom to multiple distinct fandoms.
