When I first got on , I got that a lot. I found that there was a preference button or something that lets you pick a date range. It was set on something like two weeks and I couldn't get anything.
I changed it and everything came up. Then I logged off and back on and can't get anything again. And, being an over the hill, one foot in the grave, crime scene type, I can't remember where it was.
I recommend to the moderator that you turn that button off. New people especially want to see everything anybody has written that might help.
