>I noticed that the format of the listserv messages has been changed. They no longer show who the sender is in the subject line (like: creater..replier) or the sigs at the bottom. When I read them, it'd be nice to see that without having to log into the UT. Is this a bug, or done on purpose?

This depend on the mail server being used. The one we have since last weekend does not allow us to change that field.
