what is a fanlisting?
as stated on thefanlistings.org, a fanlisting is:
a web clique that lists fans of a particular subject. Unlike most web cliques, a person does not need a website in order to join. Fans from around the world submit their information to their approved fanlisting and they are then listed to show their love for the subject.

this fanlisting...
is for lovers of Artist Trading Cards! If you're an ATC artist or collector, or just an admirer of this fabulous art form, please join!

to put it simply, ATCs are 3 1/2 x 2 1/2 inch (trading card size) original works of art. from there, the variations are endless!
