> AVOIDING INAPPROPRIATE TOPICS
> The list is open to all, regardless of profession, place of residence,
> gender, age, ethnicity, economic status, educational background,
> lifestyle, religious beliefs... but it is NOT a forum for airing opinions
> about the validity of any one particular belief system, lifestyle
> preference, etc., compared to another. Specific examples of inappropriate
> topics include:
>
> posts not related to birds, birding, and the natural world
>
> shade-grown coffee (who sells it and who doesn't; unfortunately,
> shade-grown coffee has a way of proliferating on the internet much
> faster than it does on coffee plantations)
>
> cats (pro or con)
>
> hunting (pro or con)
>
> religion (including creationism vs. evolution)
>
> Posts on such subjects all too often provoke unenlightened "debate" of a
> purely adversarial nature, and sometimes degenerate into personal attacks
> couched in terms and language offensive to the whole list. Therefore,
> these topics lie outside the Tweeters charter and are strongly
> discouraged.
>
> Other categories of objectionable postings include:
>
> chain letters
>
> virus hoaxes and other urban legends. If you believe that a virus is
> menacing the list, contact the listowner directly.
>
> commercial advertising (as distinguished from product
> endorsement). It is fine to post "I prefer such-and-such
> model of binocular," or "I want to tell you about a great
> new book," but it is NOT appropriate to say "...and you
> can buy it at Bob's Camera [or Greenleaf Books]."
> However, one-time announcements from not-for-profits
> about a new publication, or service, or event, ARE
> appropriate for posting to Tweeters.
