A slave should acknowledge and honor the superiority of her owner whenever she can. There is this... etiquette around that point:
Personal pronouns are always in lower case - i, me. my, etc - even at the start of a sentence.
Pronouns referring to Mistress are always to be capitalized: She, Her, etc.
This is an announcement as much as it is a request for help in sticking to the new capitalization scheme. It is a pretty deep habit to break and of course only applies in SL. Oy.
