There is occasional debate about switching to another site but there is so much useful info, it's hard to give it up and no way to easily migrate.
Do you get the daily email
digest? That is probably the easiest way to see if there has been a response.
For older entries, someone does a summary text file (with thousands of entries). You can download it and use search functions in word.
It would be a money
maker if Yahoo would provide a paid upgrade that saves all the old info. I'm sure the group would come up with a couple hundred per year if they added a decent interface.
