If you have an encoded picture you think others might like to see, announce this to the list and invite people to ask you directly for it. Graphically encoded text should never be posted to any list unless there is a very special reason for doing so. Run your scanned text through an OCR program or type it in, assuming that you have any right to distribute it at all. Unless you own the rights or have explicit permission from the owner, give a citation and let those who are interested look it up for themselves. General chat activity.
Virus alerts and the like.
The list owners reserve for themselves an exemption from this rule since subscribers often need to write to them about subscription-related problems. Subscribers who feel a need for discussion of these excluded topics should seek a forum elsewhere. Or form your own discussion list. We will be happy to direct you to service providers who can host such lists at modest cost. Compliance With the volume of traffic having grown to what it is at present, the list owners are not able to read every posting that is submitted.
