Because everything has to have them, really.
1. Be a fan of Boris (Bryan) Kuznetsov, either in anime or manga. Or both.
2. Use a real email address and country for joining.
3. Give a real-sounding name, no xX-GLITTER*STARZ-Xx or bEyBlAdEr_tYsOn.
4. No offensive websites. I'm open to yaoi, yuri and so on, but un-warned pornography, racist and abuse sites of any sort will not be listed.
5. Put up a code either before joining, or as soon as possible, if you want to list your website.
If you're following all that, then it's on to the joining form.
