I just added thread prefix tags to this section for "Trade" and "Sweepstakes". When you start a new thread, in the beginning of the title box, there is a drop-down menu that says "(No prefix)" by default. Click the down-arrow to the right of that and it will allow you to choose "Trade" or "Sweepstakes". I will try to update threads to include the tags as I can. Please let me know if you have any questions.
