Similar topics have come up on the orchid list from time
to time, involving plants for sale or trade, suppliers, etc.
My feeling was that a brief, public mention that "I have this
plant for sale or trade, please contact me directly", does not
represent a breach of "netiquette". I purchased some very nice
plants from a person who was down-sizing their collection in this
manner.
One thing that doesn't get mentioned nearly enough is that this list
and associated databases exist in their present form due to the efforts
of Rick Walker with the benevolence of Hewlett-Packard. While Rick
graciously lets our "discussions" follow their own course, I don't
think HP would take the same view of a list being used/abused (ie. the
recent incense message) for internet marketing or other commercial
ventures. I know the US government doesn't and since the National
Science Foundation supports much of internet you can imagine some
distubing outcomes. Just my 2 cents worth.
