About Fanlistings
A fanlisting is just what it emplies, a list of fans. While it may sound boring at first, it's certainly fun to see how widespread the fans of a certain subject are throughout the world, especially when looking at specific countries. Joining a fanlisting is just saying you're a fan of something; it's not like a newsletter or an account. The only fields that are required when joining a fanlisting are name (just first name or even an online alias would suffice), a working email address for notifying fans when they've been added to the list, and the country the fan is from. The country you're from doesn't limit you at all from joining either, but the whole purpose of fanlistings is to see how widespread their subjects are. In this case, it's Hellsing.
For more information, you can check out The Fanlistings Network's TFL For Newbies page. Remember, the whole point is to have fun with them!
