It's politeness on Usenet.  People reading your articles
	appreciate it if you follow certain guidelines.  Some of the
	guidelines are listed here.  If you are not familiar with them,
	you might want to check the newsgroup news.announce.newusers.

	Summarise or quote (briefly!) what you are replying to.
	Don't assume other people see articles in the same order you do.
	Read all replies and don't repeat what has already been said.
	Check the headers when replying and remove irrelevant newsgroups.
	Don't criticise people for their spelling.
	Cite your references if you have any.
	Don't overdo your signature.
	Try to keep your lines less than 80 characters long.
	If you reply by mail _and_ news indicate that the reply is public.
