I love this list and have learned much from most questions that have been asked. The key here is it has to relate to the Sportster. This is NOT a commercial advertisement media. Your posting must have a valid subject, or it will be returned to you. This is an important point.
Many people simply scan the subject headers to find out if they even want to read the message.
If you don't use a good subject, it may not get read by the people who can help. These will not be tolerated. These will be rejected by the listserver. Too much quoted text. Do not quote entire messages or digests in your reply.
