If you post in the Classifieds section (https://www.videogamesage.com/classifieds/) it actually will auto-post a thread in the forum for discussion. IMO it's the ideal way to post your BST threads, but there's really no "right" way, just do whatever you feel like really. Neither is more "visible" than the other, both end up with a forum thread so people will see what you post.
