@Ellen, I totally agree.
@Chris, So, you want us to have to go through the hassle, for the sole purpose of weeding out the poison? I tend to avoid making requests now, simply because of the non-responses. And the most difficult ones to deal with are the ones who are semi-responsive -- they'll respond as along as it gets them what they want, but no further.
As I responded to Robin's answer, I merely want to be aware of other people's edits to selected profiles, without having to watch entire surname tags. Most edits, I don't need to be on the Manager or Trusted list to perform. This is being collaborative.
