I'm sure this will have been said before, but all it leads to is posters resurrecting threads many months old.
On the latest one, the poster mentioned that it had popped up in her email. Why would she look at the date in that case?
Yes posters could look at the date for every thread they read, but it would be easier if the (dys)function wasn't there, and I'm not at all sure what positive purpose it's supposed to have.
