I read the posting saying Cheryl was right there. Someone brought up the Provo movie incident, and WHOEVER was posting went nutts. It was strange the way it went. The minute someone confronted Cheryl about her behavior at the movie's that evening--the posting from that end just got out of control. Yes, I believe most of the postings are done by Cheryl herself,too. I think you just pretends to be the students and says these horrible things about Leah, and the girl Annalisa (sp?) to intimidate and hurt them.
I also have my doubts if Mr.Bean/Elliot is actually posting himself. I know that there has been a conflict between this former student, his parents and the Sudweeks---so I would be surprised is this young boy is doing all this posting. I could be dead wrong, but I do not think it is Elliot.
