TEST missing & disappearing nowpublic posts?

I don't understand what is happening....  The "Santa Barbara, What Went Wrong?" posted "4 days ago" was missing, I couldn't find anywhere. I did an NEW POST, posted March 5, 2007, THERE WERE COMMENTS. Now that can't be found and the old one returned. Also missing: "Laura Schlessinger and baby of the deceased" posted March 5. And "Laura Schlessinger defiles the dead again" updated Mar 5. posted 2 weeks prior. It needed to be redone now both are missing. Should we continually repost? Does anyone have an explanation? Will they reappear? Is this a common problem?
