If it's a 6 page thread and you want to direct someone to a specific post, that's the direct url.
Maybe we're using the terminology for different things.
A post to me (and every other board I've ever been on for the past 2 decades) is the individual response, not the whole thread or topic (as it's referred to on this board), which is what I thought the OP was asking about.
Whatever. Never mind.
