I just approved you thread. You can probably expect the software to push your next few posts to the moderators for approval. (We have no control over how the software determines which posts are segregated.)
Your thread will be listed in chronological order with all the others in the Exchange sub-forum where it is posted. You cannot "bump" it. You can post to it, but it will not move to the top of the page.
If the item hasn't sold after two weeks, it can be re-listed in a new thread. (Close the old one.)
Items may only be listed in one area of the Exchange even if they might fit in more than one area, such as folder, auto, custom, etc
