Eric Siegel and John Scott have presented opposed philosophical stances regarding this issue. Neither person noted that advertising (by profit and non-profit alike) is now considered a permited use of Internet. I would only add that once a year I post a notice for a workshop which I teach once a year. I am not a non-profit; if a workshop notice from me would offend you, please set your mail program to disregard any posting from: Thompson Conservation Lab Portland, OR -or- [log in to unmask] Regards, Jack
