The neat thing is the staff have a superpower that lets us put threads in more than one forum. Make your thread, use the report button and suggest which forums you would like your thread to show up maybe with a little note about how lovely the staff are. This will draw our attention to your thread and we can work our magic.
Thanks for looking around Dean. I think if you're selling one piece of property (ideally yours) the Permaculture Real Estate forum is the place for it (Paul's link above). If you are selling lots of property or have a business, then to do advertising you'd need to investigate Blatant Advertising.
