I have enabled thread reporting. There is a small triangle with an exclamation point in it located in the lower left of a post. Clicking that will allow you to report a post for multiple reasons.
Please try to limit the reports to sold items, horrible ads and problem members/threads. In the event of an illegal item or even questionable legality please report the post and PM a moderator. For all other issues that do not require a report please use PM's.
It actually creates a new thread in the Command Room under a new section I created. So as soon as the post is reported it shows up to the staff. Tells us who reported it, why and the link to the thread.
