Single post in The Beginner's Guide - Help & Questions

Hello! I was wondering how I link to a specific post in my journal? I've seen that before, but can't figure it out. Thank you for your time! Edit* Through the PFQ wiki, other peoples posts' codes, and trial and error, I've finally figured how to link to my post. But it includes my whole journal instead of only that specific post like I've seen with other people?
