This article is from the Pratchett Newsgroups FAQ, by Orin Thomas firstname.lastname@example.org with numerous contributions by others.
The following things are advised not be done on alt.fan.pratchett. The
reasons why they should not be done are detailed here. The internet is,
of course, free and 'youcanpostwhateveryouwant' but I hope that you see
the following as an intelligent and logical set of rules.
Posting Fan Fiction to alt.fan.pratchett
It is asked that you do not post your own discworld/pratchettesque
Stories to the newsgroup. Someone might feel that an idea in a newly
released TP novel was similar to one they posted on day X. They might
even have the audacity to take TP to court on this. (this *HAS*
happened to television people on other newsgroups). To avoid the
possibility of this ever occurring Pterry politely asked that we not
post our own stories to alt.fan.pratchett. See the 'Fan Fiction
Mailing List' for where you can post your stories in safety.
Posting 'Posting Stats'
After several bad experiences it has been generally decided that
putting forward lists showing the people who contribute the most
articles to afp is a really bad idea. The reaction has been 'gosh
I only posted X articles ... better post more to improve my ranking'
This generally means alt.fan.pratchett is flooded with a higher than
usual amount of rubbish.
Posting "Test Posts"
There is a newsgroup which automatically responds to test posts
via email telling you where your news post has landed around the
world. Test posts on alt.fan.pratchett are likely to be followed
up and become long winded threads in their own right. The newsgroup
is alt.test. Although nothing is wrong with this, there is a more
effective way of testing your news server :-)
This got so out of hand that there is now a newsgroup (lspace.test)
devoted purely to afp test posts.
