[SFS] on unsubscribing (netiquette)

[David L. Willson]

Do: 
- Unsub yourself, using the link provided at the bottom of every list message.
- If you can't figure that out, ask me, Heather, or any captain, or a friend to help you.
- If you can't figure that out, send your request for help to the list, but on it's *own* thread and subject.

Don't: 
- Send your unsub message to the list.

Don't, ever: 
- Use someone else's thread to send your unsub message to the list.
