I was speaking entirely of your custom landing page here
https://www.fiatcoupeclub.org/ which is not a UBB.threads page, so as to what the query is that pulls the posts there, that'd be something you had developed unless its a post island, but it doesn't look like a post island.
For your landing page I'd recommend setting up an RSS feed in UBB.threads that queries the sections you wish to share, and use an
RSS feed parser to read that content (as the data would be cached based on settings made for the feed in the control panel)
