As a standard for "not being anonymous" on the boards, we would include sharing any pictures in links to photo hosting sites or any other kind of web posting. If you've met someone from the board in person, you are no longer anonymous. If you mention that you have a relationship with someone off the board (IM's, chat, private emails), we will assume that you are no longer anonymous.
Couple clarifications please:
1. Are married couples here considered not anonymous because they know each other? (not in the biblical sense )
Answer: As this is a precaution to prevent two people who aren't married picturing anything inappropriate, they could still be considered anonymous.
2. SIT told me about this place. I've known her online only. We met in a yahoo mom's group. We have had discussions via email and shared some family photos. Is that enough to classify me not anonymous? She also knows approximately where I live (though far from ya'll) and my real name. Just curious. Higher modification wouldn't really bother me because I don't think I post graphically.
Answer: Yes, that would make you not anonymous. But as you said, this would only apply to any kind of graphic posts, not to general moderation.
3. Would everyone that you know was invited by a friend/family here be assumed non-anonymous?
Answer: If a new person joined and said, "I was invited by Kay at our women's Bible study," and was readily able to identify you, then neither of you would be considered anonymous. However, if you mention the board in passing and they don't know who you are and you don't know them in the context of the board, then you would still be considered anonymous.
