Had to re-write the sections in the Userguide, because I remembered after merging the two Sale sections, that I can't just have new threads approved. I have to approve all posts by the junior members, which disadvantages them if they can't post in other peoples' sales (like trying to be first to buy something).
So everyone can post in the Saleyard, including new topics.
I will have to just keep an eye on new sales postings by newer members, and remove any that fail to follow the Userguide.
