There are no formal rules about what or how you should post to RAP beyond the consideration that it is supposed to be for poems and related discussion. The following points are merely helpful guidelines for those who are need some extra hints. Try not to post too much at once. A long stream of poems all from the same author can sometimes deter your readers.
People tend to skip long multi-poem posts and it makes the individual pieces harder to comment on.
You'll get markedly fewer readers if you insist on posting uuencoded Word files. Don't post your poems as attachments. Put them in the body of your post. This makes your posts hard to read and can even crash some newsreaders. If in doubt, use the title of your poem as the subject line.
