What is a fanlisting? According to TFL:
A fanlisting is simply an online list of fans of a subject, such as a TV show, actor, or musician, that is created by an individual and open for fans from around the world to join. There are no costs, and the only requirements to join a fanlisting are your name and country. Fanlistings do not have to be large sites (although some are), they are just a place where you can sign up with other fans.
If you're curious about what sort of things I'm working on at the moment on my collective, my to-do list is located here (updated Jan 10th, 2019)!
