Reporting spam / offensive posts
First if it is spam, to get immediate attention post here, also send a PM to all mods, most of us have email notification.
If it is offensive, someone has posted something in your For Sale add or is starting to argue in a thread. Pm one of us mods, and provide the member name and the thread, with a brief description. Usually it takes two people to argue, so expect at least 2 PM going out from us mods, this is time consuming and the rules stated at the bottom of each page are guidelines to follow.
