Jim, am I understanding you correctly? If someone notices that the stated purpose of a thread still contains unanswered questions or may have new, relevant meaning, he/she may simply type "refresh" without actually adding anything new, just to keep the thread from falling out of sight?
    That would be helpful to me, because I started a thread back in October and there were folks who mentioned they'd get back to it "when they had time," and it has since dropped 'way down the list. Is this such an instance?   If so, thanks a lot for your response! And if not, please enlighten me further. M.
