Yiffy international doesn't exist anymore. If you ever had an account it has been deleted.
Yes, it most certainly is. There's nothing wrong with it. I love it.

Yiffy International is an online adult furry community. To change your name on the website you will need to contact customer support. Unfortunately it is not something that can be done without their help.
Fchan(dot)us has a big deal of them Oct 2009 - A Google Group has a ton of adult gay male animations posted as GIFs. To view, you'd have to join the group, but pretty impressive variety of manly stuff. Check out: http://groups.google.com/group/Gay-Male-Animations
Furry what? If your looking for general furry art, you could try fur affinity. Sure some of it is sort of yiffy, but you work your way around it pretty easily. If your looking for a community, Furtopia is a good, clean community. I've yet to find better. If your looking for another fur you could try The Internet Furry Proximity Locater. It worked for me. If your looking for a mate, Pounced! seems to be good, though I've never used it myself being under 18. I your looking for yiff... well, I don't usually recommend yiff to anyone, but... I do know of one site that you could use... Lu.Scio.Us has a good selection of hentai, including yiff. *hangs head in shame* So I hope this helped in any way.
