As a semi-obsessive fangirl, it's pretty much obligatory for me to join fanlistings for the things I love.
Yep. Fanlistings, the plural of fanlisting: that is, a fan-listing or a listing of fans. There are all sorts of listings, but the ones I join are part of The Fanlistings Network. It's nice to declare yourself a fan of something, and nicer still to take a button (a small image used to link back to the fanlisting) and display it for all to see. If you still don't understand, I'm sure The Fanlistings Network explains it better.
