Edwin,

Many people are reporting problems with Message Search this weekend. If you check the comments in the YG Blog you will see these complaints about message search, even though the topic has nothing to do with this.:

I wish YG had a better system of communicating with members, but unfortunately this is what we have to live with. You either have to follow closely all the "fluff" in the YG blog, Various message boards, and Groups for Yahoo Groups, or you have to find someone else who does it on a regular basis and learn from them.

there's a few reasons. if you're a member the owner could have deleted the archives. there's also a known long standing glitch for message searches
