There is an R Posting Guide here:


which is a good place to start.

Generally, if you want to reply to a post and keep the thread intact, always use "reply-all" and that will keep thread participants copied, the post sent to all list subscribers, and the posts in the public archives for future use. 

Most e-mail clients (stand alone or web based) will add the "re:" prefix automatically, if not already present.

Threads are not kept intact in the list archives based upon the subject line alone, even though some e-mail clients may do so. This is why there can be a change in the subject line when using reply-all and the reply post will be kept with the original thread.

If, on the other hand, you create a new e-mail and just use "re: the original subject line" in the subject, that will start a new thread in the archive.

Don't use "reply" only to a post, unless specifically asked, as that will only copy one person, not the list nor the archives, and the communication will only be between you and that person, which is frowned upon.
