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. tfl.org
You might think, fanlistings are childish and unprofessional. From my point of view, fanlistings are the best way to practice (code) with dedication and build up a portofolio.
I am currently running 30 fanlistings, which 5933 people joined and 0 wait to get approved.
My latest fanlisting is for Gannicus » .
I joined 139 fanlistings.
