In response to Melvin Klassen, please accept my apology. I thought that you were making general recommendations to listowners rather than dealing with this one list. The best advice on the list seems to be quite brief and to the point, but wouldn't that stop Eric Thomas from sending out the details on updates and availability which is really a valuable service?
