Rule 63 is an internet rule that means "For any given male character, there is a female version of that character." This also apply to female characters turning into males. Unlike Rule 34, there are two exceptions to this rule. A: the male character is already so androgynous that a female version would be basically the same, or B: the female version hasn't been drawn yet.

Rule #357: No newbie (newbie is defined as anyone employed less than 6 months) shall send out a global email. This will prevent his inevitable embarrassment of sending information that everyone, but him, already knows.
