Now this is frustrating. Using the filter sometimes works for me and sometimes doesn't. This time it doesn't. Obviously I'm missing something.
I put Serendipity into the Filter, set the time at 2 years and pressed Go. Nothing comes up. What else does one do?
I looked in FAQ and I don't find anything in the Table of Contents with an obvious title such as 'Finding an Old Thread'. (Lots of other information, though. Thanks, Joe.)
