Hello, my favorite Audrey:
I can't speak for KD, but I think she was reacting to the original concern that "inexperienced" (for lack of better word) members were responding to posts in DID, and that some members are asking for consideration and caution when they (the "inexperienced") reply to posts in this particular forum.
I don't think she intended to be prescriptive and exclusive to the DID forum... I think she was offering it as an option for those members who WANT to limit the responses that they get.
That's how I interpreted it, anyway.
