Etiquette for posting items For Sale in R.A.S.

Just a reminder:
1. This is an international group, please include location. Not all
news reader software show the posters e-mails so even those with
country id's in their e-mail should include it anyway.
2. If possible put a price so we can avoid the inevitable "what is
the price" secondary posts.
3. On aircraft, if you have a web page or have posted info to a site
like Wings and Wheels give that information.
