None; this is a news group! That is, there are no rules enforced by the

software. There are periodically discussions on c.d.i about what should

and should not be said. This is my FAQ, so it gets my spin on the rules

that should be followed.

* Format: HTML postings are strongly discouraged; so are MIME

postings. Both cause problems with many frequently used news

readers. That means that attachments aren't encouraged either.

Also, sending the same information twice, once in HTML and once in

plain text, is downright wasteful.
