Make sure that the "Subject:" line of your post matches the topic
that you are discussing. Be concise, but specific: subject lines such
as "The Lord of the Rings" or "Tolkien" give no useful information
about the contents of your post. Note that this does not only apply to
the first post in a thread: if you see that the subject line no longer
matches the topic of a thread, change it when you reply! Also, follow
the "OT:" convention for off-topic posts (mentioned in question II.A.4
above).
When you do change the subject line, it is polite to indicate the
subject of the previous post. For example, "Balrog Wings" might become
"Balrog Flight (was Balrog Wings)" and then "Eagles (was Balrog
Flight)". This helps people follow the history of the thread.
