A participant is welcome to participate as long as it is within the guidelines (no personal criticism etc.) I don't remember reading any personal criticism. Apparently on this forum permission is not required to e-mail a person privately. For some people, support is found more on an intellectual level, by obtaining info and back and forth discussion of that info. If this is not what you want, then don't participate in it. (the back and forth discussion that is)If you are looking for emotional support in a more traditional way, post your message and I'm sure someone will answer it. There should be a place for everyone. This is my mpression of an open forum. I'm not sure what a control group forum is.
