A digest is a collection of all the posts for the day sent out as a single email. When the list traffic gets heavy, this format can make it easier to manage.
Single posts refer to each individual email sent to the list.
People are asked to include only a few lines from the post to which they are responding - just enough to clarify their response. I will write to people who regularly include large amounts or whole posts when responding and ask that they be more careful. Please be assured that I am aware when this is happening and will deal with it. P eople are sending personal responses to the list instead of directly to the person to whom they are responding. Again, please be assured that when someone is posting personal replies to the lists that teh listowner is aware of it and will deal with it.
